Look at all the blockbusters that are 3-4 hours long with intermissions...My Fair Lady, Titanic, Sound of Music, Its a Mad Mad Mad Mad World...they all were hits and were extremely long. It is possible they could have one huge movie you know, and I would like it better...however the evil marketers would earn more money with two movies...twice as much admission, twice as many concessions sold, twice as many videos and DVDs, twice as much HP themed merchandise, twice as many soundtracks...however the cast and crew would have to be paid twice also...
