After making a couple of films with United Artists, namely Follow That Dream (1962) and _Kid Galahad_, Elvis Presley returned to Paramount. Although the United Artists films had been well received by the critics, the box office was down on his previous Paramount entries. So, a conscious decision was made to return to the formula of the old Paramount films.
Stella Stevens did not want to do this movie and was nearly suspended by Paramount. Her protests hurt her relationship with the studio. She has stated several times that she refuses to watch this film.
