I just saw the movie for the first time in its entirely last night. It's really cool when you're in with an audience that's so tuned in and plugged in to what's going on.
In terms of the character itself, I can't really say that I find anything really difficult. I enjoy the character so much I don't perceive difficulty in trying to be him. It's just a matter of how do we get there.
I think when you're looking for people to interview, you want to make it fair and honest. You're not just bringing people on so you can beat them up or, you know, make fools out of them or something.
