He’s one of the very, very best at being anxious. Richard Lewis might be best known for his work on “Curb Your Enthusiasm.” With scores of other guest acting appearances and TV series under his belt, far and away his favorite was his four year run in ABC’s critically-acclaimed series “Anything But Love” with Jamie Lee Curtis. Late night television viewers, Howard Stern fans and media junkies in general are familiar with Richard’s frequent guest appearances. He may hold the title to having the most late night appearances, chalking up over 50 each on “Late Night with David Letterman” and “The Tonight Show” alone. His special, “I’m Exhausted,” aired on HBO and earned him an ACE nomination as Best Stand-Up Comedy Special. Things are definitely on an upturn. He says he, “only sees his therapist every other week now.” Recent credits include “She’s Funny That Way,” “Vamps” and “Blunt Talk.” Richard Lewis must be experienced.
