Rock Hudson turned down Sayonara (1957) and Ben-Hur (1959) in order to make this film. He later said this was the biggest mistake of his career.

The critical and commercial failure of this film caused David O. Selznick to stop producing movies.

The film's original director, John Huston, was fired after clashing with producer David O. Selznick. Cinematographer Oswald Morris quit after Selznick claimed Rock Hudson was being favored over his wife, Jennifer Jones.

An amazing number of people left the films or were fired by Selznick: John Huston, the unit production manager, one cinematographer, three art directors, one visual effects supervisor and all of the staff working in the villa hired by David O. Selznick and Jennifer Jones in Rome.

Ernest Hemingway was not shy about expressing his dismay over producer David O. Selznick casting his 38-year old wife Jennifer Jones in the role of the 21-year-old nurse Catharine in the remake of his second novel, "A Farewell to Arms". Selznick had earlier tried to generate publicity for the film by making a token payment to Hemingway for the novel, even though he was not required to do so as Hemingway had sold away the rights to his book a generation before. The gesture did not earn Hemingway's goodwill.

Ernest Hemingway hated the movie, and he bolted after thirty five minutes.

Selznick and Fox paid Universal $17,000 per week for Hudson's services.

The year the movie was released Jennifer Jones and David O. Selznick went to Pamplona to see the traditional bull run. Ernest Hemingway was also in town, and when he heard that Selznick was there he said, "I'm going to kill that S.O.B.. He ruined my book!"

Despite this film's poor commercial showing, Rock Hudson was the top box office attraction for 1957.

Vittorio De Sica had originally intended to direct the film.

Jennifer Jones was generally considered miscast as an English nurse, as well as too old for her character. It was suggested that Jean Simmons or Elizabeth Taylor should have been cast instead.
