Stuart Cornfeld is an American film producer, business partner with Ben Stiller in the company, Red Hour Productions, and an actor.
He was born in Tarzana, California. He attended the University of California, Berkeley in the early 1970s.
The appearance and personality of Les Grossman, the hotheaded and foul-mouthed Hollywood producer played by Tom Cruise in Stiller's film Tropic Thunder, is reportedly based in part on Cornfeld.
He is married to the performance artist Johanna Went.
