La isla de los hombres peces

Future director--then head of publicity and marketing for New World Pictures-- Jim Wynorski is the one who came up with the title change and tagline, and did additional filming, in order for this to be known as "Screamers" in the US.

The drawing of David Bushnell's 1775 submarine "Turtle" on the wall of the Professor's room is hung upside down.

The U.S. "Screamers" version featured not just a new opening, but several added shots and various audio adjustments throughout the film. These include several breathing sounds to give the film more of a sense of tension. It also abbreviated many scenes in the original Italian version or removed them all together. It also featured mostly new dubbing, with Claudio Cassinelli's voice replaced by an American voice actor (Cassinelli had dubbed himself in English in the original international release of the film, leaving his character with an Italian accent).

Edited into La regina degli uomini pesce (1995)
