Continuity mistake: In the end gunfight segment, the gun held by the main character is at first a revolver. When he is lying shot on the floor before his wife picks it up it changes to a regular pistol.
Character mistake: Reba opens the door for Francis, but calls him "Ralph". (01:46:05)
Suggested correction: Reba is blind and didn't know it was Francis at the door. Ralph just dropped her off, and she thought it was him.
Suggested correction: Will actually pulls two guns out of the lockbox. He fires the revolver but drops both guns when he is shot. Molly picks up the semiauto to shoot at Dolarhyde.
