Anachronisms: Right at the start, after a caption has shown that the film is set in 1966 at the beginning and the main characters are getting into a car, a radio is heard playing the song "Might just take your life" by Deep Purple. This song was released in 1974.
Crew or equipment visible: In the scene where Mirella is driving the boat out of Sicily, the bottom of another white boat can be seen when the camera focuses on Andrea.
