I've gotten such good feedback from that [re-team with Wil Wheaton for Big Bang Theory appearance], and I hardly did anything.

Basically, my deal is that I choose roles based on three criteria. One is the role, obviously, if it's something that speaks to me. Two is, are they gonna pay me? And three is, who am I gonna work with? And, really, if one of those is there, I'm pretty likely to do it, but it's particularly important to me who I'm going to work with, 'cause that's part of the joy.

The character of Brent Spiner. We certainly collaborate on the concept of that, but he basically writes the script, then it's sort of a combination of his voice and my voice.

We got to be really good friends [Jack Lemmon and Walter Matthau]. It was just thrilling, every day. Every single day. I had a big couple of musical numbers in [Out to Sea], and I remember doing one of them and shooting it from beginning to end.

Earl Mills is probably the best role I've ever been given in a film. And it was a great experience to work with Halle [Berry] and Klaus Maria Brandauer, an Austrian actor who's a hero of mine. Martha Coolidge directed the movie [Introducing Dorothy Dandridge], giving me another shot, and it was an amazing experience.

Im thinking of going into rehab. Im not addicted to anything, but I think its good way to jumpstart an acting career.

Dr. Okun. Who's named after a special-effects guy named Jeff Okun, who had done Stargate for Roland Emmerich and Dean Devlin, who did Independence Day. But "Brakish" just came up one day when Jeff Goldblum and I were improvising, and he told me his character's name and I told him mine.
