3. Lily Tomlin vs. David O. Russell
In March 2007, footage from between takes on the 2004 film I Heart Huckabees hit the 'net. Tomlin is so frustrated with Russell's constant minute changes (pick up the folder, take your legs off the table), she mouths off at the director. In one shot, Russell enters the frame, kicking, screaming and using the C word! A PA even ushers everyone off the set to avoid the crossfire. By the time they shoot Tomlin in a car, she unleashes the F-bombs on a car full of A-list costars.
