He's one of the stars of TV's most-watched comedy, but this year he's nominated for a guest shot on "The West Wing." "Interesting for funny sitcom boy to be nominated for a drama, isn't it," joked Matthew Perry from London, where he is starring opposite Hank Azaria in a stage production of David Mamet's "Sexual Perversity in Chicago."..."Especially with 'Friends' coming to an end, I'm interested in pursuing some dramatic stuff in films," Perry said. "This (the 'West Wing' role) was a great way to put my foot in that world."

Notes from "A Conversation with Aaron Sorkin" at the Museum of Television and Radio in Beverly Hills
"Part of the notion between the vice president resigning and the president's daughter being kidnapped," [John] Wells said, "was to find some way to strike at the core of the national sense of security in some way that would mirror what happened in the real world, yet not be in any way demeaning to the real events that are happening."
