Continuity mistake: At Twin Pines Mall, when Marty is recording Doc Brown, Marty is raising the video camera to record Doc Brown saying, "No, no, no, this sucker's electrical," but when this piece of film is played back in the Doc's garage in 1955 it appears as if Marty was already recording when the Doc starts speaking.
