Elvis was actually still officially dating his 1950’s sweetheart, Anita Wood, but she had grown tired of rumours about his on-set conquests, as well as reports of a new girlfriend in Germany.
Anita ended their relationship in 1962, at the same time as Elvis conveniently found himself filming a second feature with Joan, this time in California.
Kid Galahad was a remake of the 1937 film of the same name starring Humphrey Bogart and Bette Davis.
Joan played Rose Grogan, the sister of a slippery boxing promoter who spots potential in Elvis’ character, Walter Gulick, an amiable small-town wannabe mechanic.
In the film, as always, Elvis gets the girl but off-screen he had failed to persuade Joan to stay with him.
