Continuity mistake: In the scene at the cove where Suzy and Sam are talking after swimming, the flower stem over Sam's ear keeps changing positions. In some shots it's parallel to the temple on his eyeglasses, and in others it's drooping down over his cheek.
Continuity mistake: Suzy flashes white panties while getting into the tent, but is wearing red check panties later.
Continuity mistake: Redford is wearing a brown shirt with brown shorts when talking to Scout Master Ward, but has on khaki shorts when searching for Sam. (00:08:35)
Continuity mistake: In the scene where Scoutmaster Ward wakes up to an empty Camp Ivanhoe, he is without his neckerchief at the ironing board; then he walks through the deserted camp and the neckerchief is on. In the next scene, as he is ringing the bell, the neckerchief is gone again.
