Revealing mistake: When Dani goes to meet Cort after dark to go swimming, you can plainly see it's daylight out because the sun is shining.
Continuity mistake: After Dani was "skinny dipping" in the lake she is seen on the bank watching Court swim. She is supposed to be nude, but the actress is wearing a white cloth over her breasts. Its top is visible when she kisses Court.
Factual error: While the movie is set in 1957, photos of Elvis attached to a wall were taken in the mid 1960s. The orange shirt shot is from Girl Happy, 1965 and the black and white shot below it is from Roustabout, 1964.
Continuity mistake: In the end scene, where Maureen in braiding Dani's hair and they are in their bedroom on the porch, how far the braid is done differs back and forth between close up shots and the far away shots.
