He’s a divisive character, but whatever you might think of him or his views or behaviour, I’d suggest his choice of film roles is almost always good, and as a fan at premieres, he is quite simply THE nicest person. He habitually (based on two premieres I’ve been to on top of what I’ve heard) arrives AN HOUR before everyone else in the cast and crew just to make sure he can sign and pose with everyone, and has an entourage of assistants moving along, taking your camera (!) so that they can take properly composed shots with you and him in it, and he’ll sign pretty much anything and everything for everyone. He’s the first to arrive and the last to go in.
And you can’t fault him for that.
That said, it IS tricky to get a candid shot out of the guy – he is totally in character and professional throughout!
