I used to be a mean maniac. Someone once threw a firecracker at a show and I jumped off the side of the stage and whacked 'em on the side of the head.
The most difficult thing for me is a portrait. You have to try and put your camera between the skin of a person and his shirt.
As they say, there are two rules in improv: Never say no, and never ask why. When another actor asks 'Why?' or says no to something you're suggesting, then it's very clear that they're putting the onus on you, because they're not comfortable with it themselves.
