Continuity mistake: In the scene where they go to the party and dance with the sticks, there is an overhead view of the whole party. Johnny and Lalita are dancing in the middle, and just before the camera cuts to another view, Lalita drops one of her sticks, but has it in following shots.
Continuity mistake: After Bobby Darin loses the Academy Award for supporting actor, he and Sandra Dee argue and threaten to leave one another. Sandra Dee jumps into her pink '63 Cadillac Coupe Deville and roars away as Bobby Darin jumps into his red '61 Cadillac Convertible and futilely tries to start it. The car's battery fails, and we see the four headlights flicker and go dark. Enraged, Bobby Darin jumps out of the convertible and begins smashing the car with a golf club. When he starts smashing out the headlights, all four lights are now glowing brightly.Charles Austin Miller
