Kristy McNichol took up smoking as part of the preparation for the role, but couldn't quit the habit. She was a regular smoker for nearly 10 years after finishing the movie.

When the girls first get their cabin assignments, Penelope says that Cabin C is for Little Kids (10-year-olds). Later, when Cinder is taking the bets, a much-older girl hands her money and says that Cabin C is betting on Ferris to win.

Marianne Gordon is listed in the credits as Mrs. Whitney. The actress filmed scenes as Ferris Whitney's (Tatum O'Neal) mother but her scenes were cut from the film. They gave her the credit as a courtesy!

NBC broadcast this film in early 1983 (and reran it in mid-1984) using an alternate version complete with originally cut footage to replace the risqué material as well as sloppy dubbing to cover up all traces of "virginity loss". In one case, when Cinder asks Sunshine to "play something sexy" on her flute, the dubbing changed the line to "play something SULTRY." In place of "whoever loses her virginity first--wins!" came the change "whoever gets a guy first--wins!" There was also a fairly large scene brought out of the vault which had Angel saving Ferris from drowning after Ferris' boat capsizes in a storm. Other new scenes: the hijacked bus breaking down just outside of Camp Little Wolf, forcing the girls to walk back with the condom machine; Miss Nichols asking each of the girls if they know anything about one of the campers being involved with Mr. Callahan; the girls going to Miss Nichols to confess their story (to get Gary out of trouble), including a reluctant Cinder (sporting a black eye from Sunshine's sock to her face).
