His distaste for the movie cannot be expressed by merely pointing out how dumb it is, though. Affleck begins to make fun of absolutely everything on-screen, like he's having a gradual mental breakdown while watching it. He starts making fun of Billy Bob Thornton for his grunty simpleton role in Sling Blade (like, a whole bunch). He starts making goofy noises to mock the stuntmen during the film's action sequences, which creates one of the most awkward moments in DVD commentary history:
Ben: "Stunt acting is always fun to watch. [doing mock voices as stuntmen dive away from an oil rig disaster] Whoooaaah! Arrrghhh!"
Bruce: "My stuntman, Terry Jackson, was almost killed on this film. He was hit in the head with a big piece of pipe. The only thing that saved his life was the fact that he had a hard hat on."
OK, the actors weren't in the same room during the commentary, so he wasn't saying that directly in response to Affleck. Bruce Willis has witnessed the near-death of so many stuntmen that it's probably how he begins every sentence.
