The Perfect Actor for The Role

I was watching an episode of the BBC series New Tricks and David Haig played the role of a 'baddie' in the episode and he seemed very familiar. I was reminded that he played the role of the gun ho special branch detective in Rowan Atkinson's sitcom 'The Thin Blue Line' but I was doing some research today and it hit me that David would be the ideal actor to play the role of James Connolly. What do you think?
