Lisa Kudrow

Kudrow was cast to play the role of Roz Doyle in Frasier, but the role was re-cast with Peri Gilpin during the taping of the pilot episode. Kudrow said in 2000 that when rehearsals started, ''I knew it wasn't working. I could feel it all slipping away, and I was panicking, which only made things worse.'' Her first recurring television role was Ursula Buffay, the eccentric waitress on the NBC sitcom Mad About You. Kudrow would reprise the character on the NBC sitcom Friends, in which Kudrow co-starred as massage therapist Phoebe Buffay, Ursula's twin sister.
