A director's cut of this movie was released in 1997 with 5 additional minutes. This cut is identical to the original British release version (100 minutes): the film was shortened by five minutes for its original American release.
To receive a 'AA' (14 and over) UK cinema certificate the BBFC requested cuts to remove full frontal nude shots of the girl during the swimming scene. However the cuts were rescinded upon appeal and the film was released uncut.
A version screened by the BBC in the early 80s featured some Easy-Rider style scene transitions (rapid cuts back and forth) not found in the other cuts.
