I have been reading a lot of articles and info about the Doctor Who episodes to be screened at Christmas and as I did I came across this article from the Daily Mail:
Master of the Loonie-verse: Craziest Dr Who villain ever says his final showdown with David Tennant will scare us all witless.
In it he mentions LoM, saying that:
No less amazing for Simm was being whisked away for Life On Mars through a time warp to Seventies Manchester, a place close to where he was born and raised.
But perhaps the best thing about Life On Mars for Simm was the chemistry he shared with Philip Glenister, who played the fabulously un-PC DCI Gene Hunt opposite Simm's 21st-century cop.
'We more or less lived together for the two years of Life On Mars; it was like we were married! We never got tired of each other, we just moaned together like grumpy old men. I adore him. I'm very proud to have been part of a cop double act that had that chemistry because it's such a rare thing.
'It really worked, all that jumping over bonnets, chasing people in cars. It was such a laugh.'
Although Simm, at first, threw the script of Life On Mars in the bin, deeming it too weird, he came to realise it was 'a hell of a great part'. So leaving wasn't easy.
'I thought: "If they stop it now, it will be a classic. Like The Prisoner." My story had come to a natural end. Plus, Gene Hunt was such a huge character. There are only so many times you can roll your eyes and tell him off.'
If there is any remorse, it's to do with the American remake starring Harvey Keitel as Gene Hunt and Jason O'Mara as Sam Tyler.
'I'm not even curious,' says Simm wryly. 'I am Sam Tyler and that's it!' Simm laughs, but insists the same applies to the U.S. remake of the TV political thriller State Of Play, in which he starred on TV with David Morrissey.
