There were crazy fans there and he managed to be kind to them while still not indulging their crazy, which I found admirable. Nobody asked about the arrest or anything, but he made a couple of references to it and was just a smart, interesting person.
Sounds like we had very similar experiences. He was especially kind to a couple of kids who were there. He let one 8 year old take his picture and spent a lot of time answering a 13 year old who asked if he had any advice for an aspiring filmmaker and actress. He asked her about the short film she said she'd made and then gave her what I thought was some real grown-up advice: 1) Don't get into it unless you have such a passion for it that you can't imagine doing anything else, and 2) You need to find a way to get satisfaction for what you do from within yourself. Applause isn't always going to be there, so the only way to be happy in this business is to satisfy yourself.
