Who Is Martin Mull?

Martin Mull is one of those faces that's so familiar, and yet I knew so little about him. He's Colonel Mustard in 'Clue', Gene Parmesan in 'Arrested Development','Principal Kraft in 'Sabrina the Teenage Witch' (iconic), and yet it turns out all he really wanted to do was paint. Bob Saget started to make this documentary before he died, and it was completed after Mull passed. It features a ton of other incredible comedians, musicians and artists, some of whom are also now gone, so there is a bittersweet element, but at its heart its a real celebration of art and life.
