 The length of time it took to make the film, which was unheard of at  the time, was due in part to the unwillingness of the US Navy to  endorse the film. Without the Navys endorsement, it would have been  impossible for the filmmakers to use naval equipment and personnel.  The Navy was concerned that the films subject dealt with a mutiny,  and that audience would feel that it was a true story. But the  filmmakers reached a compromise upon agreeing to include the comment  in the opening titles that there has never been a mutiny on a US  Navy vessel.
