I heard an interview with Francis Ford Coppola In which he expressed his hesitancy in making The Godfather due to it's emphasis on some sexual content.  He agreed to make it when it was considerably toned down.  Having read the book, I think he totally made the right decision.  I don't have any particular aversion to sexual content but in this case I certainly agree with Coppola.  I then though about Jaws and it also benefited by the sexual content of the book being eliminated.  I can think of several cases where the opposite has been true also.  Battleground comes to mind where after a serious illness that could effect the character's sexual performance, the movie version has swimming instead of sex which missed the point.  Can anyone think of other movies where the inclusion or exclusion of sexual content changes the quality of the film?
