Togo - // I heard an interview earlier where "Gloria" or at least the guy who played him in It Aint Half Hot Mum said that in real life he was nothing like the character he played but was a real gentleman and very kind. //
That, I guess, is the sign of a good actor.
I remember seeing Ben Drew (musician Plan B) playing a villain in the film Harry Brown (excellent film) and I could really hate him - but a friend who knows him says what a genuinely lovely guy he is.
Similarly, Martin Kemp has a nice line in baddies, espeically as Reggie Kray, and I know he is a lovely guy.
