Das Grauen aus der Tiefe

As the film was being finished up, producer Roger Corman felt that the picture needed more sex, nudity and monster shots throughout, so he ordered scenes shot that showed the humanoids attacking and ripping the clothes off of other nubile young women. Director Barbara Peeters, who was a feminist who hated that idea, refused to shoot the scenes. Corman said he'd hire a second director and get her feedback before using the new footage. She agreed to that. But Corman ended up never showing the new footage to her or the cast and other crew. They didn't see them until the preview of the film. Peeters was furious, protesting that they were inserted purely to show gratuitous nudity. Corman also edited out many of the scenes dealing with the plot and character development in order to make room for the nudity and more creature scenes. Peeters complained that it was no longer the film she made and wanted her name taken off. Corman said he'd do that but only if she paid the expense of redoing the credits. She wouldn't, so her name stayed on the project. Many years later, Peeters ended up watching the film on cable and admitted it actually ended up being "a fun little movie."

Once the humanoids break through the bottom of the dock, the commotion starts. And the first eight or nine seconds of screaming is "looped" and continually heard throughout the rest of the attack at the carnival.

The US Blu-ray release from Shout! Factory has the scene with man's head being ripped off intact.
