 Although most of screenwriter Noel Langley (I) (qv)s ideas were  used in the finished film, and he is credited as being the principal  screenwriter as well as the adaptor, there were some revisions to  his material. Langley was incensed that they had been done, and  walked out on the project several times, although he was always  persuaded to return. He was bitterly resentful of the final  screenplay, and is on record as saying that he hated the finished  film when he finally saw it.
