The 1949 film:
- California Doubling: Some scenes were shot on sets at Pinewood studios in England.
- Executive Meddling: A wedding scene had to be filmed in order to appease The Hays Code.
The 1980 film:
- Creator Backlash: Brooke Shields felt uncomfortable at being a sex symbol while she was underage, and was one of the many reasons she didn't have sex until she was twenty-two.
- Dyeing for Your Art: Christopher Atkins permed his hair to look more "savage".
- Hauled Before A Senate Subcommittee: Brooke Shields, who was fourteen at the time of the movie's filming, had to testify before a Congressional inquest to confirm that she never actually appeared nude on screen.
- What Could Have Been:
- It was the director's original concept to have the two grown characters play the entire film in the nude, which scared off many actors. (Not canon, either. In the novel, they both wear clothes pretty much as they do on the screen. Em's skirt, designed by Paddy to let her keep wearing it as she grows, is described at length; he based it on a sail with reef points.)
- Rosanna Arquette, Kim Basinger, Justine Bateman, Linda Blair, Jamie Lee Curtis, Carrie Fisher note , Bridget Fonda, Jodie Foster, Melanie Griffith, Daryl Hannah, Anjelica Huston, Amy Irving, Sarah Jessica Parker, Jennifer Jason Leighnote , Michelle Pfeiffer, Dana Platonote , Molly Ringwald, Kathleen Turner, Debra Winger note and Sean Young.
- John Belushi auditioned for Richard, but he was deemed "too funny" for the role. Sean Penn and John Travolta also auditioned. Richard Gere and Sylvester Stallone were also considered. Christopher Reeve auditioned, but turned it down due to his commitment to Superman II.
Return To The Blue Lagoon:
- Box Office Bomb: Return was one of these. Its production budget of $11 million was sullied by its box office total of $2,807,854.
- Creator Killer: The failure of Return to the Blue Lagoon at the box office destroyed William Graham's career, as he never made a theatrical film again, as well as writer Leslie Stevens (who only wrote one more film before passing away). It also put the breaks on any Blue Lagoon adaptations for nearly 20 years, and even then it was only a made-for-TV film (The Awakening).
- Old Shame: It's best not to mention Return to Milla Jovovich.
- Real Life Writes the Plot: The movie was shot in chronological order. At the start of filming, the weather wasn't as nice, which paralleled Sarah's struggles raising the two children at first.
- Reality Subtext: As a child model, Milla Jovovich had been compared to Brooke Shields. She plays the role of Emmeline, which had been played by her in the original movie.
- Troubled Production: Unpredictable weather changes threw a wrench into filming early on - with two solid weeks of heavy rain. They also had to shoot extensive sequences in the surf with the child actors during these conditions. Although the weather eventually improved, the cast and crew had to be treated for all sort of tropical diseases across the shoot.
- Dawson Casting: Both the leads were in their early 20s playing high school students.
- Fake American: Australians Indiana Evans and Brenton Thwaites play the American teenagers.
- Remake Cameo: Christopher Atkins appears as one of the teachers.
- Retroactive Recognition: In The Awakening, Jacob Artist (Jake Puckerman from Glee) is the school quarterback, with a minor role at the start of the film.
