Karl Tiedemann, a New York City native, studied film production at NYU. One of his short films—King of the Z's, a parody documentary about a low-budget movie studio co-created with Stephen Winer—led to joining the writing staff of NBC's "Late Night with David Letterman." He later worked on series for NBC, the Disney Channel and others. He has performed extensively in comedy clubs as half of a team and is currently a regular member of "Sunday Night Improv," an ongoing comedy show at Broadway's Homegrown Theatre. Television appearances include the Letterman show, "Robert Klein Time," "America's Funniest People," "Kwik-Witz," "Cosby" and, most recently, TV Land's "Sixty Second Sitcoms." Tiedemann spent a year at Jacques Lecoq's theatrical school in Paris and participated in clown workshops with Dominic Jando of the Big Apple Circus. Articles by him have appeared in The National Lampoon and elsewhere, and he has taught comedy writing and improv at New York's New School. His award-winning comedy-thriller Alias the Fox has been produced regionally, and his latest comedy, Off the Hook, co-written with Allen Lewis Rickman, was produced in 1999 in both New Jersey and Vermont. Tiedemann is a member of The Dramatists Guild of America and Writers Guild of America, East.
