Philip Glenister is "scared" of his co-star Bernard Hill.
The 51-year-old actor - best known for his portrayal of police officer DCI Gene Hunt in 'Life on Mars' - has admitted to feeling intimidated by the 69-year-old actor, who plays his father in new BBC One drama 'From There to Here'.
Bernard was specifically chosen for the part by scriptwriter Peter Bowker to match the macho personalities of Philip and his on-screen brother Steven Mackintosh.
Philip told The Sun newspaper: "Peter Bowker said they had two alpha males with me and Steven. So they needed someone that was going to scare even us. There was only one man for the job - Bernard.
"He certainly scared the life out of the crew when he parked his car on somebody's lawn. It was the first day of the shoot and he insisted on driving to set and he drove straight on to the lawn of his onscreen house."
Fortunately, Philip's nerves were put at ease by his former 'Life on Mars' co-star Liz White - who plays his love interest Joanne in the new show - and he says there is a "chemistry" between the pair.
He explained: "Liz and I worked together on 'Life on Mars' so it was fantastic to be back together.
"She's so easy to work with and it does help that there's a chemistry there."
The three-part series - which follows the aftermath of the 1996 IRA bombing in Manchester - starts tonight (22.05.14) at 9pm on BBC One.

Mike Myers is obsessed with painting KFC icon Colonel Sanders.
The 'Austin Powers' actor has always been fascinated with the mascot and viewed the fast food as "exotic" when he was younger, and now finds himself sketching likenesses of the famous face on a regular basis.
He admitted: "I make about a painting a week. I started painting about two and a half, three years ago.
"My first painting was of my wife, Kelly. My second one was of my dog, George Harrison. And then I got into this Colonel Sanders thing.
"Growing up in Canada, looking south at America, they are so amazing at creating identity that they even have enough leftover to come up with the colonel who is the colonel of chicken!
"Our whole family was obsessed with the Colonel. For me show business was buying Kentucky Fried Chicken. Because it was nationally advertised, and it seemed exotic. First of all, it's a great character.
"He has his own unique silhouette--you can draw him in three lines. On the day that Lucian Freud died, I painted my version of a Freud with the Colonel, naked, holding a palette, painting himself. Then I did the Colonel with the Pearl Earring. Then I did the Colonel Lisa. You know, which is the Mona Lisa with the Colonel. This is so just a hobby. It is just making stuff. That's all I want to do, is just make stuff.
"[Do I still paint him?] Oh yeah. Yeah, I do. It's just a fun constant."
The 50-year-old actor - who has son Spike, two, and daughter Sunday, six weeks, with wife Kelly - also enjoys making music at home on his computer.
He added in an interview with America's GQ magazine: "I also make GarageBand tunes. I make one a day. I have now for eight years. They usually end up sounding like the Pet Shop Boys. And the Lightning Seeds, and a bit like Joy Division, and it can sound like Kraftwerk. I made one this morning. I called it 'Just Let Me Have My Steel-Belted Radials'."

Tori Spelling ordered her nannies to take time off while she was in hospital.
The reality TV star was treated as an in-patient for six days for a migraine last month, leaving husband Dean McDermott - who has admitted to cheating on his wife last December - to take care of their kids Liam, seven, Stella, five, Hattie, two, and Finn, 20 months.
A source told RadarOnline.com: "Dean was forced to take care of the kids on his own, at Tori's direction. They employ two nannies, one part-time, who takes Liam and Stella to school, picks them up, and helps with homework.
"The other nanny is full time and helps Tori at home with the younger children, Hattie and Finn. It was so typical of Tori to do, and extremely passive aggressive. She also told the crew filming to not help Dean at all with the kids, as they have done when Tori is home. As soon as Tori came home, the nannies reappeared."
The 'True Tori' star - whose latest reality show is chronicling the couple's struggles to save their marriage - is also said to have stopped her spouse spending much time in hospital with her.
The source added: "She wasn't going to allow it. Tori demanded that he take care of the kids....there is absolutely no reason why Dean couldn't have gone with her, or visited more. He very much wanted to, and the fact that the producer was calling to give him updates speaks volumes about the status of their relationship."
Friends of the couple have now slammed their behaviour, insisting they are letting their problems get in the way of their children's needs.
The source said: "The two of them are extremely messed up, and have tons of insecurities... The fact they have four innocent kids that they are exposing to all of this chaos with the cameras is just selfish and disgusting."

Mark Wahlberg wants his children to "trust" him.
The 42-year-old actor - who has kids Ella, 10, Michael, eight, Brendan, five, and Grace, four, with wife Rhea Durham - thinks it is important to have a close relationship with his family so they aren't "terrified" of him, but he insists that doesn't mean he won't administer discipline when needed.
He said: "I think the most important thing is to always be involved in every aspect of their life. To give them enough trust that they can share things with you. I don't want them to be terrified of me, you know?
"But I don't want them to think they can do whatever they want and get away with it, either, because they can't."
The 'Transformers: Age of Extinction' star - who spent time in prison when he was younger - is proud of his success but worries his wealth means his kids won't "appreciate" things in the way he did when he was younger and growing up in a poor area.
He told the new issue of Esquire magazine: "The biggest thing for me is, you know, as quickly as I was able to turn it around, to get from there to here, from me having nothing as a kid to me here now, providing everything for my kids, it's like, I worry that maybe they won't appreciate things.
"I worry that maybe they'll have a sense of entitlement. You don't wanna give your kids everything without giving them the tools to be great people."

Courtney Stodden "punched" the first guy she kissed in the face.
The 19-year-old starlet - who split from Doug Hutchison, 53, after two years of marriage last November - was just eight years old when a classmate with a crush on her "cornered" her in the playground, and she admits her response to the smooch was "a little violent".
Recalling her first kiss, she said: "I was about probably eight years old. I was in first grade and the boy who had a huge crush on me, he would run around the playground and he would chase my around and I thought he had cooties. So one day he cornered me and kissed me and I was having none of it and I literally punched him in the face. So my first kiss experience was a little violent."
The blonde beauty can't bear being around insects or spiders and gets "freaked out" if she sees a bug.
Asked her biggest fear, she told Fox411: "I hate to say the old classic spider thing. I can't stand termites, I can't stand roaches, and insects. All of that stuff freaks me out. I'm such a little girl when it comes to bugs and termites, that kind of thing. So anything that's creepy and crawly, it freaks me out."

James McAvoy felt like he was filming a sex scene on his first day on the 'X-Men: Days of Future Past' set.
The 35-year-old actor plays a younger version of Charles Xavier, who was first portrayed by Sir Patrick Stewart in the original 'X-Men' trilogy, and when the pair were on set together he felt like he was in an initiation ceremony where the legendary actor was handing over the "baton".
However, since there was few cast and crew around, unlike the usual bustle, it was like they were preparing to shoot intimate scenes.
Talking on XFM radio station, McAvoy said: "Although I'd previously played Charles in one other movie, it still did feel like I was being initiated and that there was a baton being handed over. It was a very kind of ceremonial scene, in a very sort of ceremonial location. We were in a monastery, and the set was very quiet, and the director made sure that... It was much more like a sex scene.
"You know that when we do sex scenes we make sure there's nobody on set. It's just the boom operator, the camera man, and you don't have loads of people staring at you... usually we do!
"And it was a bit more like that. Clearing the set, making it very quiet, very reverent, that was kind of cool. It felt like I was being initiated into some kind of superhero sect!"
McAvoy joked about raunchy scenes with Stewart being a part of his "wish list".
show host Jon Holmes asked: "You didn't worry that they were clearing the set, thinking, 'Is this a sex scene I hadn't red in the script, with me and Patrick'...?"
And McAvoy replied: "A sex scene with Patrick Stewart would be exceptional. Tick that one off the wish list!"

Guns N' Roses are rumoured to be splitting up.
Frontman Axl Rose is said to be planning to call time on the hard rock group after they complete their Las Vegas residency on June 7, almost 30 years he created the band while living in Los Angeles.
A source told RadarOnline.com: "Band members have been told their calendars are free following Vegas.
"Axl is considering retiring and it's done. Band members and support staff were surprised when told the news and are actively looking for work."
The 52-year-old singer is the only remaining founding member of the band with lead guitarist Slash, bassist Duff McKagan, drummer Steven Adler and rhythm guitarist Izzy Stradlin having all quit over the years.
The current members of Guns N' Roses are Tommy Stinson, Dizzy Read, DJ Ashba, Frank Ferrer, Chris Pitman and Ron 'Bumblefoot' Thal.
The 'November Rain' hitmakers, who have sold more than 100 million records worldwide, begin their Las Vegas residency on May 21, playing nine dates at the Hard Rock Hotel and Casino.
Another source said: "Axl has made enough money and wants to stop touring. He is considering retiring."
However, Loudwire.com is reporting that a source has told the site that the split rumours are "bullsh*t" and the band members are taking a break, giving them chance to focus on other projects.
Bass player Duff - who quit Guns N' Roses in 1997 - briefly rejoined the band in April, standing in for Tommy for five shows across South America.
Axl and Slash have barely spoken since the guitarist quit the band in 1996 due to a breakdown in their songwriting partnership and the collaborative process between the entire group.
Their rift only worsened when Axl refused to join the other original band members at their induction into the Rock 'n' Roll Hall of Fame in February 2012.

Fatboy Slim still 'loses control' on stage and admits "rave demons" take over.
The 'Eat Sleep Rave Repeat' hitmaker, who has been one of the biggest names in dance music for more than 20 years, has been sober since entering rehab in 2009 for alcohol addiction and insists although he no longer drinks, he enjoys his shows more and still gets lost in the moment.
He told the Daily Star newspaper: "I cherish the shows more now. It's nice, actually being able to remember them afterwards. Before, it was me and the crowds having a big party together.
"It's still a party, but I feel directly involved now, and having been a DJ for so long I know how to press people's buttons to get them dancing.
"But I still lose control on stage, especially in the last half-hour. The rave demons take over, and I find myself doing dance moves I didn't know I had in me."
The 50-year-old star, real name Norman Cook, lives in Brighton with wife Zoe Ball, 43, and children Woody, 13, and Nelly, four, but insists he likes to ditch his dad image during festival season and will be heading to the likes of Creamfields and Glastonbury this year.
He said: "Once I'm on stage, I go from being responsible father-of-two to a giggling 15 year old, hell bent on mischief and hedonism.
"The crowds keep me young for those two hours on stage. But as soon as the show finishes, I'm spent. I'm knackered and go straight to bed."
The star also claims his teenage son Woody has started to realise his dad has the "coolest job in the world" and no longer finds it cringe-worthy.
He said: "He was perpetually embarrassed and would say, 'All you do is play loud music to a load of drunk people who shout at you', I'd go, 'Well, yeah, that is my genre'.
"But he came into the DJ booth at a show in Ibiza last summer and he started to feel the same intoxication I get from music. He told me afterwards, 'Dad, I'm beginning to get what you do now."

The Rolling Stones' former manager Prince Rupert Loewenstein has died.
The music industry veteran, who is credited for turning the fortune of the group from near bankruptcy to billions when he started working for them in the 1960s, passed away on May 20 after suffering a long illness, according to Independent.co.uk.
Prince, dubbed "the human calculator", managed the band - made up of Keith Richards, Mick Jagger, Charlie Watts and Ronnie Wood, along with former members Brian Jones, Ian Stewart, Bill Wyman and Mick Taylor - for four decades, before they parted on amicable terms in 2007.
In his memoir, 'A Prince Among Stones', he admitted he wasn't interested in rock and pop music but wanted to help The Stones during financial difficulties.
He wrote: "I certainly felt that Mick was a sensible, honest person. And I was equally certain that I represented a chance for him to find a way out of a difficult situation. I was intrigued.
"So far as the Stones' music was concerned, however, I was not in tune with them, far from it. Rock and pop music was not something in which I was interested. I had heard some of The Beatles' music.
"Their music was sufficiently harmonic to be acceptable to people such as me. I only really took against rock 'n' roll when I heard the Stones.
"But the offer to look at the Stones' financial situation had come at a very good time for me both professionally and psychologically."
His funeral, which is expected to be attended by members of the band, will be held on Friday, May 30.
Prince's passing follows the tragic death of L'Wren Scott, the fashion designer girlfriend of Mick, who committed suicide in March.

The Mayor of a French village has pleaded with Britain's Prince Charles to visit during the 70th anniversary of the D-Day landings.
Olivier Paz, the mayor of Merville in Normandy, claims he and the people of his village were under the impression that the 65-year-old royal would be visiting his town during the upcoming anniversary, but after meeting with the heir to the throne's aides at Clarence House yesterday (21.05.14) he was told they were never on his schedule.
Speaking to The Local newspaper about his disappointment, the mayor said: "The people of Merville are very upset. We had been preparing for the visit for weeks.
"We though he was going to come so our expectations were high and then to be let down at the last minute. There was so much enthusiasm, people had been preparing their British flags. That's why everyone is so upset."
Mayor Paz also confessed another reason he was hoping the Prince of Wales - who is currently returning from a four-day tour of Canada - would finally make a visit to his town.
He added: "We have never had a visit from a member of the Royal Family and this may be the last chance as there may be no veterans left by the time the 75th anniversary comes around."
