Last summer I met the entire cast of Chris and John to the rescue, which is a TV show on the logo channel. They were all pretty cool. But, there were a lot of other people there as well.
It was a cast party, and they were filming a series
I also met an actress from the movie Pleasantville at a film festival. (I can't recall her name) She was pretty nice, and answered some questions I had about maybe being an actor.
I also met a guy from Buffy The Vampire Slayer. Plus several other actors, one who currently has a sitcom.
I also know a few porn stars if that counts.
