 Samuel Fuller (qv) submitted a screenplay that was almost  completely different from what was filmed. Among other things, the  Lee Marvin (qv) character was not a sheriff, but a KKK leader  whose racist viewpoint is completely changed around. However,  Paramount got nervous about the provocative nature of the screenplay  and ordered it rewritten, infuriating Fuller (who left the project  because of this) and Marvin (who wanted out but had already signed a  contract.)
