Jon Hamm used to work on porn films.
The 43-year-old actor struggled to get his big break in Hollywood when he first started out in the 90s and took every job he could find, including the "soul-crushing" role of a set dresser for soft-core porn movies.
He confessed in the new issue of Vanity Fair magazine: "I was actually at that time working as a set dresser for Cinemax soft-core-porn movies. It was soul-crushing."
Years later, after slaving away as a waiter and being dropped by his first agent, Jon landed the role of slick advertising boss Don Draper in hit 60s set show 'Mad Men' and he has never looked back.
He explained: "This is the best job I've ever had and maybe ever will have in my life - it's so fun to play all of this. It can be relentlessly dark. It can be terribly sexually inappropriate, is a way to say it. But who else gets a chance to do any of that stuff? There's so much there."
The handsome star's passion for acting harks back to his childhood, when his father would take him along to parties and dump him in front of the TV all night.
Jon recalled: "Eleven-thirty would roll around and the big huge 22-inch TV would be tuned to 'Saturday Night Live'. I would sit two feet in front of the TV and stare and watch the whole thing."

Janelle Monae didn't like the audience at Coachella Valley Music and Arts Festival.
The 'Tightrope' singer joined OutKast on stage to sing with Big Boi at the event in Indio, California last month, and while critics claimed the show failed to live up to expectations but Janelle blames the crowd.
She told Faster Louder: "I didn't like that Coachella audience.
"I'm happy I got to CounterPoint [Music Festival] in Georgia, because those were real festival-goers, in my opinion."
Janelle joined Andre 3000 at the CounterPoint Music Festival to dance on stage during 'Hey Ya!' last weekend and gushed about the band who have reunited onstage after a near decade-long hiatus.
She said: "That is my favourite duo, favourite rap group ever invented.
"They were in their time travel machine and they came back to see us, and I think we should all be grateful that they came back. "The music is more fun, and lives are enriched with those two ATLiens performing. They're also great friends of mine, so it's great to see your friends do what they love doing and get the love and support they need."
Outkast collaborated with Monae on two tracks from their most recent album - 2006's 'Idlewild' - and she also made an appearance on Big Boi's 2010 solo album 'Sir Lucious Left Foot: The Son of Chico Dusty'.

Michael B. Jordan "geeked out" when he was cast in the 'Fantastic Four' reboot.
The 27-year-old actor will play the Human Torch - a character who can absorb fire into his own body and is able to fly - in the forthcoming film and insists he and writer/director Josh Trank, who he previously worked with on 2011's 'Chronicle', acted like they were discussing their next "science project" when they were in talks about the production.
Talking to vibe.com, he enthused: I was like 'Oh shit. Man, that is ridic-- really? You want me to play that guy? Okay, cool.' It was just us two guys, two fanboys, just geeking out over the possibilities, or how it's going to be, and what we should do here, what we should do there, and the ideas we had for it. It just like two best friends just sitting there talking about our next science project. It was a lot of fun, a lot of excitement. I was excited. I was geeked."
Although Jordan wants to make his portrayal unique he admits there are certain elements of the beloved superhero which he must stay true to.
He added: "There are certain characteristics that people look for in the Human Torch that makes him unique. You gotta respect the past a little bit, and you also gotta respect the present and the future and give your own take."
He will be joined by Jamie Bell as Ben Grimm aka The Thing, Miles Teller as Mr. Fantastic and Kate Mara as the Invisible Girl.

Katie Price's pregnancy is very different to her previous ones.
The 35-year-old former glamour model has just discovered she will give birth to her fifth child in three months time and says the news came as a shock because she hasn't experienced any of the symptoms she had when carrying her other four children, Harvey, 11, Junior, eight, Princess, six, and Jett, eight months.
She said: "I had no idea I was even pregnant. I always laughed when people said that they never realised they were pregnant. I've had four kids and it happened to me.
"I usually put on loads of weight and you can only just see my bump now. I've had no cravings and I'm not eating ice cubes like I have with all the others.
"I don't even feel pregnant. But I really want to start to show my bump off. It's going to be gone soon, so I want to make the most of this bump."
Katie - who knows the sex of her new baby - insists all her family are excited about her shock pregnancy, but she still thinks it is "crazy".
She told Now magazine: "We've gone through such swings of emotions so it feels now we can all start really getting excited. This baby is going to be in the same school year as Jett because they'll be less than 12 months between them. It's completely crazy."
And though the six months pregnant star wasn't expecting to have another baby so soon, she still wants more children in the future.
Asked if baby number five will be the last, she replied: "No way. I want more kids. I'm going to start again when I'm 40 but I think I need to give myself a rest before I get going again."

George Clooney's fiancee thought his proposal was a joke.
The 'Monuments Men' actor - who is known for his love of pranks - asked lawyer Amal Alamuddin to be his wife over dinner at his house last month, but he had to pop the question twice as she initially didn't believe he was serious.
A source said: "George has been blown away by her passion, her brains, and sheer force of will.
"Frankly, he's been worried that someone else would snap her up if he didn't act, so he produced the ring and. much to his relief, she said yes.
"But he did have to ask her twice! Amal thought he was pranking her at first. Happy isn't a strong enough word to describe them right now."
The couple are said to be planning an intimate wedding in Italy this summer, with just a select few guests invited to the nuptials.
A source said: "The important people will be there, but this is private, not for public consumption, so it will be friends and family only.
"It was a long time coming, but when George commits to something he really sees it through. Amal is the one."
The 53-year-old hunk has resigned from his United Nations (UN) role as a messenger for peace, and friends say that is because he intends to team up with Amal, a human rights lawyer, for a new project.
A source told Grazia magazine: "He's hitching his wagon to Amal's so he wants a clean slate in every sense.
"They're not just planning to live together, they're planning to work together too. As a team they could be unbeatable."

Neil Patrick Harris has lost 22lbs.
The 40-year-old actor admits he has shed some weight over the past few months in order to play the titular role in the Broadway musical 'Hedwig and the Angry Inch'.
Speaking on 'Live! With Kelly & Michael', he said: "I'm skinny. When I was filming 'How I Met Your Mother', I knew this show is coming up and it's such a different type of role that for three or four months I've been doing nothing but cardio and trying to lose some weight ... I lost about 22 lbs."
Neil - who has their three-year-old twins Gideon and Harper with his fiancé David Burtka - lost the weight by switching to a healthier diet and eating at a different time.
He explained: "It was pretty much a combination of [diet and exercise]. I just stopped eating late. I was the kind of person who, after we put the kids down, we would go eat at like 9pm or 9.30pm. We would order food in and by the time we ate, it was 10ish. It's easier with kids because kids eat dinner around 5.30 or 6pm. And we would just eat with them and I would try to not eat later."

Hayden Panettiere fell down the stairs after the Met Gala on Monday night (05.05.14).
The 24-year-old actress took a tumble at the Metropolitan Museum of Art in New York City earlier this week after her glamorous Tom Ford dress got caught up under her feet.
The 'Nashville' star was making her way out of the annual event, held by Anna Wintour, when she stepped on the back of her dress and toppled over.
However, the blonde beauty managed to elegantly save herself from landing on the ground and revealing her knickers, before smiling sweetly at photographers.
She continued down the stairs after the mishap but made sure she lifted up the frock so that she didn't make the same mistake again.
Meanwhile, Hayden recently revealed she and her fiancé Wladimir Klitschko were delaying their wedding due to the current fighting in Ukraine, as the boxer's brother, Vitali, is involved in the reform efforts over there.
She said previously: "Everything that's happening in Ukraine definitely put a hold on things. But we have time."
The couple started dating in 2009 and announced their engagement in October last year.

Miley Cyrus asked her fans to "snog" people of the same sex during the first London show of her 'Bangerz' tour.
The 21-year-old singer, who was hospitalised last month for a severe allergic reaction, appeared to be back to her usual self as she kicked off the European leg of her world tour at London's O2 Arena last night (06.05.14).
A source told the MailOnline: "She got loads of same sex people to snog in the audience and put them on camera on a giant screen and make a speech about how we should all just be ourselves.
"She said she hopes we are all drunk and on loads of pills and at one point her dressers had to come on stage as her corset was undone while humping midgets."
Lily Allen took to her Twitter account after the show to say how much she enjoyed the energetic set.
She tweeted: "That was basically the best thing I've ever seen #BangerzTour #MileyCyrus (sic)".
However, Miley's revealing costumes and sexy dance moves didn't suit everyone's taste and one person claimed her friend had walked out of the gig.
Claire Louise tweeted: "One of my old work friends has walked out of the Miley Cyrus show at O2 cos she was being vile and disgusting....no shock there then (sic)."
The 'Wrecking Ball' hitmaker was forced to postpone a number of US shows and the first two shows of her European leg last month due to ill-health.
However, despite still battling with the illness, Miley is scheduled to perform five more dates in the UK before moving onto Ireland and finishing up in Chicago.

Kim Kardashian hasn't married Kanye West yet.
The 33-year-old star has shot down rumours she and the 36-year-old rapper tied the knot in a private ceremony in Los Angeles over the weekend after allegedly securing their marriage license last month.
When asked if she's already married Kanye, she told a reporter at the Met Gala in New York City on Monday night (05.05.14): "Still Kim, Mrs. West soon."
Meanwhile, the couple - who have 10-month-old daughter North together - are set for a wedding extravaganza with their friends and family in Paris on May 24.
However, it is believed the loved-up duo will be forced to legally wed in California before their romantic bash in Paris after it was revealed the French law requires a strict 40-day residency before they can get married in the country.
The brunette beauty has been busy preparing for her big day in the romantic city and recently admitted that she's chosen her wedding gown after trying on "quite a few".
She said: "I tried on quite a few. [Then I] narrowed it down."
The couple announced their engagement in October 2013 after year-and-a-half of dating.

Monty Python have unveiled a previously unheard track.
The comedy troupe premiered 'Lousy Song' today (06.05.14), which will feature on the upcoming re-issue of their classic 1989 album 'Monty Python Sings (Again)'.
The track was performed in 1980 by Eric Idle and hears Graham Chapman, who passed away in 1989, interrupting the recording to declare how much he dislikes it.
Speaking about the song, Eric said: "It is the only totally improvised sketch I can remember Python doing.
"Graham enters the recording studio when I'm listening back to a song I have recorded. I think it is very funny."
'Monty Python Sings (Again)' is set for release on June 9 with a box set of all their recordings, including three never-before-released songs and three new recordings.
'Monty Python's Total Rubbish: The Complete Collection' will then follow on June 30 and will feature all nine UK-released 'Monty Python' albums.
The new releases will coincide with 10 live shows at the O2 Arena in London in July, which will be the last time the veteran jokers will all perform together.
The reunion, which kicks off on July 1, will see Eric, Michael Palin, John Cleese, Terry Gilliam, and take to the stage for the first time since 2009.

Britney Spears has been sued for allegedly breaking her backing-dancer's nose during rehearsals last year.
Dawn Noel has filed a lawsuit against the 32-year-old singer after she accidentally whacked her in the face while practising for her 'Work Bitch' music video at a studio in Woodland Hills, Los Angeles, on August 19, 2013.
Ms Noel claims the 'Hit Me Baby One More Time' hitmaker arrived two-and-a-half hours late for rehearsals "in a dishevelled and confused state".
She went on to state the choreography for the dance was "fairly basic", but Britney appeared to be having "difficulty learning the moves and following simple directions."
Ms Noel claims she was standing to the side of Britney when the star "twirled in an unbalanced and reckless manner, arms extended out to her sides and forcefully backhanded" her square across the face.
The lawsuit, obtained by E! News, alleges that there was a "cracking sound", known immediately to be Ms Noel's nose, that was heard by other dancers.
Britney allegedly said sorry after the incident, before continuing with the dance routine.
Ms Noel sought medical advice half an hour later and was told she had a nasal fracture that would require surgery.
The lawsuit states that Britney and Reign Deer Entertainment agreed to pay for the medical bills, but Ms Noel was informed months later that wasn't the case.
Ms Noel is suing for serious physical and emotional damages and is demanding a jury trial.

Justin Bieber has sparked rumours he's dating a model.
The 20-year-old hunk was spotted getting cosy with Yovanna Ventura, 18, yesterday (05.05.14) as they rode in a rickshaw through Venice Beach, California.
The pair were seen acting "like a couple" on the beach boardwalk, where they "had drinks and snacks", before Justin drew even more attention to himself by putting his hand on Yovanna's thigh while they rode the bike.
A source told E! News: "Their relationship is blossoming. I wouldn't be surprised if they have now started dating."
The duo have known each other since March after the stunner caught Justin's eye on Instagram and he reached out to her, before meeting her a few weeks later in Miami.
The source added: "It's been killing her she couldn't tell anyone about him. Meeting Justin has been exciting for her."
It appears the feelings are mutual as the 'Baby' hitmaker reportedly enjoys her company and likes talking to her.
The source explained: "Justin really likes her. I think he really enjoys being around her. She is just such a genuine person and he likes to talk to her."
However, the news that Justin's found himself a new love interest might not go down well with his former flame Selena Gomez, whom he has been dating on/off for three years, as she reportedly "flipped" out last month after the star was getting too friendly with her pal Kylie Jenner.
