Elmer Bernstein wrote an hour of music for the film, much of it progressive and experimental, but most of it was unused after the opening sequences until the film's last half hour. Bernstein removed some of the cues himself after the film was extensively re-edited because they did not work in truncated form while others appear to have been removed by producer and replacement director Stanley Donen. The full score was released as a very limited edition CD in 2008 that is now deleted.
Lord Lew Grade objected to two scenes he felt were distasteful and had them cut out of the picture. One scene had Hector mutilate Benson's corpse on a laboratory table whilst the other was a dream sequence where Alex and Adam murdered Benson.
A few years after the release of the film, Farrah Fawcett was a guest on The Tonight Show Starring Johnny Carson (1962) in which Mr. Carson casually poked fun at Fawcett's movie choices. "I remember you did a picture - I think it was called 'Saturn 3'." The audience laughed a bit as Fawcett squirmed, answering, "Originally they had a very good script, it was called 'The Helper', and it was a lot different from what we ended up shooting."
This was the first production that Farrah Fawcett was again billed as Farrah Fawcett and not as Farrah Fawcett-Majors after her separation / divorce from Lee Majors. Before this marriage, earlier in her career, she had previously been billed as Farrah Fawcett.
Stanley Donen on John Barry's abrupt departure "It was my fault, not John's. The truth is John had hardly ever been on a set, which I didn't realize. He was such a terrific talent, but he'd spent most of his time in an office. He knew next to nothing about staging a scene, or handling actors. And since nature hates a vacuum, the actors jumped on him. The film started floundering. Finally I had to tell him : 'it's not working. I'll have to be on the set with you'. I had a moral commitment, after all ; I'd make sure the film went all right. But when I did turn up on the set, John said he just couldn't work like that, so he left. There was no question of his being fired."
In his novel "Money" (1984) Martin Amis uses a great deal of his experience as the screenwriter for this film as the basis of the book. The director, John Self, is based on the film's original director John Barry, and Lorne Guyland (Long Island in Newyorkese) is meant as a caricature of Kirk Douglas, the aging star still trying to prove how sexy he was. Caduta bears some resemblance to Sophia Loren, who, fortunately for her, was not a member of the film cast.
