 Half of the clips shown in the trailer for the film are not in the actual  movie.  The scene where Colin Hanks is making a video to send to Stanford and  Jack Black interrupts, giving him advice on how to do it better, is not in  the film at all.  Also, many of the scenes in the classroom with the English  teacher are not included, like the discussion about Friends and great poets  like Jewel and Eminem. Many scenes featuring Jack Black that were shown in  the previews are not in the movie (when hes lying on the couch and changes  the station to Spongebob Squarepants and also when he and a dog are fighting  for a hot dog).
