The Cher song
"Half Breed" was inspired by this movie. The songwriter, Buddy McCubbins, said he saw it when he was a sexually charged adolescent and jacked it, thinking about Pearl, countless times.
Another interesting bit of trivia: Butterfly McQueen said that once, on set, Gregory Peck put a cigarette out in a nearby open beer can, then Jennifer Jones came along, picked it up and drank it and never said a word.
