Q: We get a kick out of the Mr. Noodle character on "Sesame Street." Has he done other comedic work? What is the actor's real name?A: The character in the "Elmo's World" segments of "Sesame Street" is played by the multitalented Bill Irwin. He has been nominated for Tony awards as an actor, director and choreographer and writer, and won a 2005 acting Tony for "Who's Afraid of Virginia Woolf." He has co-starred in "Waiting for Godot" with Steve Martin and Robin Williams and has been the creepy killer Nate Haskell on "CSI: Crime Scene Investigation," in addition to other stage, TV and screen performances. (For example, you can also see him with Williams in Bobby McFerrin's "Don't Worry, Be Happy" video, and with Martin in "My Blue Heaven.") In 1984, he received one of the "genius grants" from the MacArthur Foundation; he is also in the International Clown Hall of Fame. He has been playing Mr. Noodle since 1998.
