Upon seeing it for the first time, Ernest Hemingway walked out after the first 25 minutes. He criticized most aspects of the film heavily, and said the only good thing about the film was Errol Flynn's performance.
Fans of Tyrone Power were shocked by his tired and aged appearance in the movie, since he was only 42 at the time of filming. Years of chain smoking cigarettes and drinking heavily had taken a toll on his looks. In addition he was reportedly taking pills so he could survive with only three hours sleep every night.
As detailed in his autobiography, "The Kid Stays in the Picture", both cast and crew, Ernest Hemingway, Tyrone Power, and Ava Gardner included, attempted to have Robert Evans fired during production. Producer Darryl F. Zanuck refused, saying, "The kid stays in the picture," thus leading to both Evans' long career as a producer and the title of his book.
There was an Australian documentary on Errol Flynn's life and career, narrated by Christopher Lee. It included an interview with Flynn regarding his Academy Award nomination for his critically acclaimed performance in "The Sun Also Rises." We are then told that the nomination "disappeared".
Mel Ferrer and wife Audrey Hepburn saw Juliette Gréco singing in a Paris nightclub, and they introduced her to Darryl F. Zanuck. He was so taken with her that he cast her in the film and had her part enlarged -- and reportedly began a relationship with her. She went on to star in two additional Zanuck productions. Mel Ferrer had actually appeared with Juliette Gréco in Elena and Her Men (1956) the previous year.
