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.
