Trivia

Elvis' red sports car in the film is a one-of-a-kind 1959 Chevrolet Corvette XP-87 Stingray concept car. Originally silver in color, this car was the design inspiration for the "C2" generation of Corvettes (1963 - 1967), which took the name "Stingray" from this vehicle. The Stingray was modified for the film (in addition to the red paint, a hood scoop was added). Since filming, the car has been restored to its original condition and color, and is a museum piece worth several million dollars.

Although this film was set in Miami, Florida, Elvis Presley's scenes were all shot in and around Los Angeles, California. All the Florida exteriors were shot in wide angles, using doubles and look-alike impersonators for Presley.

While shooting this film, Elvis suffered a serious fall in his bathroom at home, tripping over an electrical cord and striking his head on the porcelain edge of a bathtub. The resultant injury was serious enough that Presley lay unconscious for an unknown length of time, and was briefly hospitalized. The pain-killers he was prescribed to relieve the massive headaches and other effects of his injuries began the drug dependency that was partially blamed for his death a decade later.

Elvis Presley had so much debt in early 1967, due to his purchase of a Memphis ranch with up-to-date equipment, that his manager, Colonel Tom Parker, had to sign the contract for this movie in a hurry so that Elvis could get his one million dollar fee. This was the last time Elvis would get the magic million dollars.

One of the children at the playground during the song "Confidence" is Corbin Bernsen.

Lee Majors: visited the set. He can be seen in the background of the restaurant scene, wearing a fake mustache.
