When Mike McCoy (Elvis Presley) crashes his white AC Cobra into the water it suddenly changes into a Mistral-bodied Austin-Healey.
At the beginning of the song "Adam And Evil", a bass guitar on a stand is seen on stage. When the song ends, the bass is no longer there.
At the start when Cynthia Foxhugh (Shelley Fabares) in her sportscar is seen approaching Elvis from behind in his sportscar, she is clearly approaching him so fast that she will pass when she pulls to the side of him, but when the camera cuts when she is just behind him she is somehow then seen merely driving alongside Elvis and not well out in front of him.
