Yellowbear is a 1983 comedy film, that was co-written and acted by Monty Python member Graham Chapman, Peter Cook, Bernard McKenna and David Sherlock, and directed by Mel Damski. The film co-starred Peter Boyle, Cheech & Chong, Madeline Kahn, Peter Cook, Spike Milligan and Marty Feldman (in his last film appearance). Fellow Monty Python members Eric Idle and John Cleese also starred, although Cleese only played a part out of loyalty to Graham Chapman. He has said that he found the script to be one of the worst he's ever read. David Bowie had a cameo as The Shark.
