Mechanic told him, “this film is wildly out of control. Nothing is going to change that. All we can do now is contain it. So here are some scenes we’d like you to cut from the shooting schedule.” Cameron studied the list of scenes, and immediately refused to cut any of them.
“If you want to cut my film,” James Cameron told the president of Fox, “you’ll have to fire me, and to fire me you’ll have to kill me.” Then he stormed off set. The scenes stayed in the picture. Mechanic had little choice but to relent: No other director could manage all the moving parts Titanic required.
I am not particularly attached to Titanic myself, but I find Cameron's passion to be completely infectious.
