Joel Kinnaman had trouble peeing in his 'RoboCop' suit.
The Swedish actor had 45lb of armour applied to turn him into the cyborg policeman every day of filming on the new movie - a process which took an hour and 45 minutes - and he needed help taking certain bits off every time he had a toilet break.
He told E! News: "There was a procedure. It took a while, but you get through it. They didn't have to take me [to the bathroom] but they had to remove certain parts, the essentials."
bathroom difficulties aside, Joel admits wearing the heavy armour plating made him look cool.
He added: "It made me feel badass. But it also made me feel some of the vulnerability that the character was going through and that was an interesting contrast of emotion, being amputated from the throat down but at the same time having this almost invincible incredible new body. The suit helped me understand some of those thoughts."
Joel, 34, also said playing RoboCop fulfils one of his boyhood dreams, as he was a huge fan of the 1987 original, directed by Paul Verhoeven.
He said: "[It came out] sometime when I as nine or 10 years old. I've seen it like 20 or 25 times. I know it by heart. I loved it and still love it."

Jason Derulo gave Jordin Sparks 10,000 roses for Valentine's Day.
The 'Talk Dirty' singer went one better than Kanye West - who gifted his wife-to-be, Kim Kardashian, "a thousand" roses - by filling a suite at the Redbury Hotel in Los Angeles with the bright red flowers.
He wrote on Twitter: "10,000 roses fill this suite! I only wish I could've fit 10,000 more in here! (sic)"
Jordin, 24, was amazed by the lavish gift when her fiance surprised her with them.
She tweeted: "Completely overwhelmed by 10,000 roses today from, my love, @jasonderulo. They're so beautiful! Omg.... (sic)."
Jordin then posted another photo of them together with one of the bunches, adding: "Preeeetty sure my face says it all. I love you babe!"
Romantic Jason, also 24, also played matchmaker on the romantic day on Friday (14.02.14), as a member of his audience proposed to his girlfriend while he performed his track 'Marry You' at the Nokia Theatre in Los Angeles, as part of a Valentine's Day concert.
He also shared the flowers he and Jordin aren't able to keep with other lovers, tweeting: "Happy Valentines! I'm glad we were able to give the excess of the 10,000 roses away after the surprise. Spread the love ya'll."

Kendall Jenner has flown to London to host a birthday party for Harry Styles.
The reality TV star - who is rumoured to be dating the One Direction singer - arrived in the UK over the weekend, where she is said to be teaming up with Harry's friend, radio DJ Nick Grimshaw, to organise a wild celebration at The Box nightclub in London.
A source told the Daily Mail newspaper: "They are throwing Harry a belated 20th birthday party.
"It's a sign of how far their relationship has come that she and Nick, one of Harry's closest friends, are doing it together. They have many surprises planned."
'Story of my Life' star Harry turned 20 on February 1 while in California, where he had a low key day celebrating with Kendall, 18, at her father, Bruce Jenner's mansion in Malibu.
The singer's 19th birthday was a wild affair, with him partying with Nick at trendy London club Alibi where they ran up a £5,000 bar tab and Harry received a lap dance from a stripper dressed as a policewoman.
A source said at the time: "It lasted about 10 minutes but the girl stayed after and chatted to guests. She took her clothes off but kept her bra and pants on. They wanted to embarrass him."
Despite insisting they are not dating, Harry and Kendall have been inseparable over the last few months, flying between the UK and the US to see each other and even going on a short ski holiday.

Emma Watson fell ill after Darren Aronofsy banned water bottles on the set of 'Noah'.
The filmmaker wanted to encourage a "pro-environment" atmosphere during filming to echo the messages of the movie, which led to the "delirious" actress drinking "stagnant" water in a bid to stay hydrated in the early morning heat.
She said: "Because of the storm, Douglas [Booth] and I ended up shooting most of our scenes between 4am and 7am - and at that time I never function well.
"Because the film has a pro-environment message, Darren didn't want anyone drinking from plastic water bottles on set either. So that made things slightly harder.
"Everything we used had to be recycled or recyclable. Having no water bottles on set at five in the morning - when you're exhausted and delirious - wasn't ideal.
"I was so tired one morning I picked up a mug from my trailer and drank some stagnant water that had been there for the duration - so three months. I was so ill."
And the 23-year-old actress was stunned when the director told her to "use" her illness in the scene.
She continued to Wonderland magazine: "I came in the next day and was like, 'Darren, I don't think I can do this, I'm really sick.' He was like, 'Use it for the scene.' And I turned round to the bus and was like, 'Is he joking? He is joking right?' and there was deadly silence."
Filming was often tough on the movie because of extreme weather conditions, and the heat even saw Ray Winstone come close to passing out on set.
Douglas said: "We started filming in the summer in New York. It was so hot that Ray Winstone at one point, who wore a beard and heavy make-up, nearly fell down a flight of stairs."
Emma added: "His make-up was literally melting off his face. Then we decided to shoot the soaking wet scenes. We literally went through all the seasons."

One Direction have developed people skills since becoming famous pop stars.
The 'Little Things' hitmakers - consisting of Harry Styles, Niall Horan, Liam Payne, Zayn Malik and Louis Tomlinson - are currently the biggest boy band in the world and they think their confidence has soared since they took part in 'The X Factor' in 2010.
Liam, 20 said: "I think for me - and for you, Zayn - we weren't that confident and because you have to talk to so many people it gives you so many more people skills. When I used to go to family parties as a kid I couldn't hold a conversation. Even with my own uncle. So it's nice that I've now got those skills."
Zayn, 21, added: "It's really built our confidence and our social skills. We do find it a bit easier to carry ourselves and speak to people - it's cool."
However, Niall and Harry, both 20, have joked that it's all "downhill" for them now because they've reached their twenties and have started coming into their own.
Niall said: "Like getting on stage - last year alone we did over 100 shows. So that helps with confidence. But I think we've all become our own people now because we're at that age where we're all turning 20 and we are who we are now, I guess."
Harry added to We Love Pop magazine: "We're over the hill, he's trying to say. It's all downhill from here!"

David Walliams was called 'Davina' as a child.
The former 'Little Britain' comedian has admitted he was given a "feminine" dressing gown by his uncle, and it led to the family making jokes when he came downstairs in the mornings.
He told The Sun on Sunday newspaper: "My uncle bought me a feminine silk dressing gown. So when i came down to breakfast I was called Davina."
The 42-year-old star also revealed how he was nicknamed 'Daphne' while at school after he raced around the playground pretending to be Wonder Woman.
He added: "I got a reputation for being a tiny bit effeminate."
Recently, David showed his support for Davina McCall, who is competing in a Sport Relief triathlon.
He previously told BANG Showbiz: "I think it shows that in these challenges you are pushed to the absolute limit. But I know she's quite a strong person both mentally and physically.
"The best way we can get behind her is donating, because that'll be the biggest thing that will make her happiest, to know people are behind her and care."

Susanna Reid will take over as ITV's new breakfast show host.
The presenter is currently employed by BBC, but it is said she has been offered a £1 million deal to switch to their rivals as she looks to front her own show.
According to the Sunday People newspaper, Susanna will end her time on 'BBC Breakfast' after the broadcaster refused to promise her a higher-profile role.
It is said she will front a new early morning show on ITV - likely to be titled 'Good Morning Britain' - with new Director of Daytime Helen Warner keen to give her the chance to move away from breakfast TV is she decides to go down that route.
An insider said: "Susana is seen as the future of ITV. She is loved by millions.
"She's beautiful, intelligent and warm. She is seen as more highbrow than previous presenters who fronted the breakfast shows, which is exactly the direction ITV wants to go in."
A spokesman for ITV has insisted while changes are soon to be revealed, they remain keen to keep current 'Daybreak' host Aled Jones as a "key part" of the channel's future.
They said: "There has been a review of ITV breakfast. Some changes will be announced. Aled remains a key part of plans."

Benedict Cumberbatch looks like a "vaguely attractive" otter.
The 'Star Trek Into Darkness' star says he has a "weird face", and joked it has certain animal-like qualities despite many people being impressed.
Speaking to The Hollywood Reporter, he joked: "[There is a] blessing of having a weird face, somewhere between an otter and something people find vaguely attractive. Or just an otter which is vaguely attractive."
Benedict also insisted he thinks his success has made him more attractive than his "face", explaining he's only just started turning up "on these 'Hottie' lists".
He added: "In all seriousness, I grew up with this face and it's been in the industry for 10 years and now it's getting on these 'Hottie' lists.
"It doesn't make any sense because I was nowhere near the thousandth hottest face when I started out. So, I know a lot of it's projection, which is flattering about the work."
The 37-year-old actor doesn't consider himself "a typical beauty", joking his combination of "a long neck" and face typically means "inbreeding weirdness".
He said: "When I started out I said, 'I know I'm not a typical beauty', so basically I've got a long neck and a long face.
"That's usually some kind of inbreeding weirdness. So, I'll run with that. I'll wear some high collars and get on a horse or two. I'm fine with that, but not all the time.
"Sometimes I'll just get a collar in a 21st century drama and I'll turn it up, as you probably noticed in 'Sherlock'."

Rita Ora says she will "never" quit singing for acting.
The 'How We Do (Party)' hitmaker recently filmed scenes for her role in the upcoming blockbuster 'Fifty Shades of Grey', but she has no intention of completing a permanent switch to Hollywood.
She told Ahlan!: "Singing is where it all began for me. I love it and without doing that first I would never have managed to get anything else.
"I enjoy everything I do, but in five years time I will still be singing, that I promise you. I will never stop singing."
As well as her role in the erotic thriller, she has also appeared in the likes of 'Fast & Furious 6'.
The multi-talented star recently revealed she was "homeless" after leaving her flat due to her neighbours getting annoyed when she started to record her upcoming second album there.
She said: "Do you want to know something funny? I'm actually homeless right now.
"I had to leave my flat because the neighbours didn't like me that much. I'd been recording my album there, which is not a really good idea. Long story short, I now live in my sister's flat."

Sylvester Stallone made a surprise appearance at the Broadway preview of 'Rocky'.
The action movie veteran - who starred in the film versions of the boxing saga - shocked audience members when he showed up at the stage version of his 1976 blockbuster.
A source told New York Post newspaper's Page Six column: "Stallone made a surprise appearance at the end of the show and even stepped into the ring."
He posed alongside actor Andy Karl - who plays the hero in the stage production - as 'Saving Mr. Banks' star Tom Hanks led the audience in a 'Rocky' chant.
Sylvester, 67, climbed into the ring at the Winter Garden Theatre in New York City to celebrate the first performance of the new musical.
Recently, he paid tribute to Metro-Goldwyn-Mayer as the studio celebrate its 90th anniversary last month.
He said: "Once upon a time this amazing studio employed the finest creative minds in showbusiness.
"The most accomplished writers, actors, celebrated directors and producers found a home at MGM. I did and I was lucky enough to show up with this guy we called Rocky Balboa, and the character was born under the MGM banner.
"We may have had the 'Eye Of The Tiger', but it was the lion that put us on the map and made it all happen."

Kylie Minogue wanted to quit 'The Voice' because she didn't like rejecting the contestants.
The TV talent show mentor admitted having to turn down hopefuls on the show was difficult, and ending their dreams made her consider quitting.
Speaking at a Spotify music event, she said: "It can get you down a bit trying to think of ways to say no because no one wants to say that.
"The fun bits of being a coach are really fun but during the not fun bits you just don't want to be there."
Kylie explained she "doesn't really like decision-making", despite her high-profile role as a judge on the BBC singing contest.
She revealed: "It's intense. You think you're just never going to come up for air again because the days are very long.
"And for someone who doesn't really like decision-making, all day is decision-making."
However, the 'I Should Be So Lucky' hitmaker has been given the BBC's word that the contestants - whether they were successful or not - are "taken care of".
She explained: "The BBC assured me they have never had complaints from any of the contestants.
"They really get taken care of so well, whether they go through or they don't. They leave with a lot of experience."

Suzanne Shaw says 'Dancing On Ice' has taken over her life.
The former Hear'Say singer won the skating contest in 2008, and admitted training for the current All-Star final series means she hasn't seen "friends for family" unless they've come to watch the show.
She told The Sun on Sunday newspaper: "I love doing this and I don't want to wish it away but I have had to be disciplined off the ice.
"I've not seen my friends or family at all unless they've come down to watch me skating on Sunday nights.
"Last week I had three messages from friends on the same day, all saying, 'I've not spoken to you in ages.' "
While the show is a big deal for Suzanne, she is still making time for her son Corey, nine, and her mother - although she isn't getting to spend much time with boyfriend Sam Greenfield.
She admitted: "My priorities are skating, my mum and my nine-year-old son, Corey.
"I didn't do anything with Sam for Valentine's Day - I went home after training, put my PJs on and watched some 'Breaking Bad'. Luckily he understands it isn't forever."
