I've seen two shows that Haig Sutherland has been in: Alice, I Think and Robson Arms. I knew that he was in both shows before I saw them, but when I saw the second one (Alice, I Think), I wouldn't have recognized him if I hadn't known what character he was playing.
That's a good thing in an actor, I think. He's so completely different in each role, that he's unrecognizable, which means that he's able to play all sorts of roles.
As I said, I've only seen him in the two, but they're completely opposite roles, and he's played them both well. He should be in more tv roles!moreless
