10 Movie Stunts That Went COMPLETELY Wrong

There's no denying that Brad Pitt more than earned his paycheque during his collaborations with noted perfectionist David Fincher.

Despite the director's infamous penchant for countless retakes, apparently Fincher is open to improvisation when it comes to the welfare of his actors. At least, that might explain why he told Edward Norton to punch Pitt in the ear, instead of the where the actors had previously agreed on, in order to prompt a more authentic reaction during the filming of 1999's Fight Club.

Then again, maybe Fincher just wanted revenge for everything Pitt put the production of Se7en through when he injured himself onset.

The cast that his character is wearing throughout the film? Pitt earned it for real by planting his arm through a window during the filming of one dramatic sequence.

The scene was being filmed early in production and soon saw Pitt slice his hand open, breaking a bone in the process and necessitating the cast for the rest of the filming process.

Even the simple stunts can go terribly wrong.
