Nightmare Beach - La spiaggia del terrore

Umberto Lenzi, originally hired to direct, had a falling out with the producer just as production started and wanted to be taken off the film. He stated in a 1996 interview that he found the story "too similar to his earlier film Sette orchidee macchiate di rosso (1972)" and decided before shooting began that his name would not appear on the film. Screenwriter Harry Kirkpatrick, also known as James Justice, was given the job of directing, and received sole directorial credit, though he convinced Lenzi to remain on the set in an uncredited advisory capacity throughout the entire production. For years, many horror film fans thought Harry Kirkpatrick was an alias for Lenzi, but Lenzi has stated in interviews that there really was a Harry Kirkpatrick who wrote & co-directed that film. He explained, "My contribution consisted solely of providing technical assistance. Nightmare Beach - La spiaggia del terrore (1989) should be considered the work of Harry Kirkpatrick."

When Skip and Ronny are checking in the hotel, a woman can be seen walking behind them, but in the next shot, she is still walking, but even more behind them.

In order to get a FSK-18 rating, German VHS release by Skyline Video was cut by almost a minute to reduce some violence. Despite that, the BPjM still indexed the movie which results in various sales and advertising restrictions. The DVD and Blu-ray releases in Germany are uncut, although released unverified (distributor didn't bother with a FSK re-rating test) despite no longer being indexed since 2015.
