Pre-production
The film's original director was Arthur Penn, who resigned after a dispute with Chayefsky. Special effects expert John Dykstra also resigned. The film was produced originally at Columbia Pictures, who would later end their participation with the film, before Warner Bros. bought the film. Chayefsky later withdrew his name from the project; film critic Janet Maslin, in her review of the film, thought it "easy to guess why":
- It's easy to guess why he and Mr. Russell didn't see eye to eye. The direction, without being mocking or campy, treats outlandish material so matter-of-factly that it often has a facetious ring. The screenplay, on the other hand, cries out to be taken seriously, as it addresses, with no particular sagacity, the death of God and the origins of man.
Film critic Richard Corliss attributed Chayefsky's disavowal of the film to distress over "the intensity of the performances and the headlong pace at which the actors read his dialogue."
Russell maintained that he changed almost nothing in Chayefsky's script, and called the writer "impossible to please."
