Who is Bill Irwin? People tend to think of him as an actor, a dancer, a performance artist, a vaudeville clown. But he's also a producer, director, writer, and choreographer. Sometimes it's sort of hard to describe exactly what Bill does, but people who have seen him agree - he does it well.

• Bill plays Mister Noodle on the "Elmo's World" segment of SESAME STREET.
• He's "that other guy" in Bobby McFerrin's video of "Don't Worry, Be Happy" with Robin Williams.
• The Regard of Flight , which aired as part of PBS's GREAT PERFORMANCES series.
• Northern Exposure, where he played "The Flying Man" who wooed Marilyn in seasons 3 ("Get Real") and 4 ("On Your Own").
• His wonderful solo dance in the movie My Blue Heaven, starring Rick Moranis and Steve Martin.
