Shirley's highly dubious trivia

This appears in the trivia section:

While appearing in a nightclub act with his wife at Lake Tahoe, Gordon MacRae received an emergency phone call to replace Frank Sinatra as Billy Bigelow in the film version of Richard Rodgers's and Oscar Hammerstein II's stage hit Carousel (1956), after Sinatra walked out before filming. Originally, it was said that Sinatra left when he discovered that every scene was to be filmed twice - once for regular CinemaScope and once for CinemaScope 55. However, Shirley Jones later revealed that the real reason Frank Sinatra left was that Sinatra received a call from Ava Gardner, who was in Africa with Clark Gable shooting, Mogambo. She'd said something to the effect that if Frank Sinatra didn't fly to her immediately, she was going to have an affair with Clark Gable.

Within three days MacRae, who was already familiar with the Broadway show and had wanted to play the role, reported to the set. Ironically, the producers then discovered a way to shoot in CinemaScope 55 and then convert it to regular CinemaScope without filming the movie twice.
