Francis Ford Coppola showed a screening of this film to Paramount executives in order to convince them that Al Pacino was suitable for the role of Michael Corleone in The Godfather.
When the screenplay for the film was submitted to the MPAA for a ratings evaluation, the board declared that it would receive an X rating for the language alone. The final film was rated R.
Jerry Schatzberg turned down the script when he was offered it by the production company. He was then re-approached when Al Pacino took an interest in the project. He agreed then to direct on the condition that Pacino could star, however ironically it then became difficult to find a studio that would back the project with a newcomer like Pacino.
