So... Colm Meaney as Gene Hunt in US- Life on Mars?
Chief O'Brian?
I mean, I love Miles O'Brian, but... I have difficulty imagining the chap who plays him saying things like 'You're surrounded by armed bastards!' or referring to people as Dorothy. Or, come to that, with an interrogation based on punching people in the stomach.
Maybe I'm underestimating him, but I really don't see it.
