HOLLYWOOD — "Boy, you're bringing back an experience where I got fed up and pretty tired of myself!" exclaims Sam Rockwell on the topic of the sci-fi cult film "Moon," which he dominates more than any other single actor has done in a movie for years.

"The funny thing is, when all that (experience) was over, I was glad to see the back of me, as it were. I really wanted to go back to being just one actor out of a whole bunch of actors. But now, time has passed and, well, if someone sent me a great script about identical twins, I wouldn't automatically say no.

"That's how life is: you get tired of something and swear off it, but then eventually you miss it and you're ready to sort of repeat the whole situation."
