Some trailers use " special shoot " footage , which is material that has been created specifically for advertising purposes and does not appear in the actual film . The most notable film to use this technique was '' Terminator 2 : Judgment Day '' , whose trailer featured an elaborate special effect scene of a T-800 Terminator being assembled in a factory that was never intended to be in the film itself . Dimension Films also shot extra scenes for their 2006 horror remake , '' Black Christmas '' - these scenes were used in promotional footage for the film , but are similarly absent from the theatrical release .

However , after the September 11 attacks the studio pulled it from theaters
