Elvis supposedly enjoyed making this film because he played in a scene where his character was playing football with the guys. This is a sport that Elvis loved doing in real life with his buddies at home.
Publicity stills for the movie featured Elvis and Marilyn Mason posing with guns a la Bonnie and Clyde in front of cars. Including 1960s Cadillacs. Despite the fact that neither use guns in the movie and that it's set in 1927.
Elvis Presley typically appeared in every scene of his movies. This film's unusual structure - including a number of guest stars and a plot that unfolds through the eyes of two children - resulted in two unlikely yardsticks: the fewest Presley vocals in all of his musicals, and the film in which he has the least amount of screen time.
