Alternate versions

In Mexico, in order to catch major audiences and avoid censorship, two versions were released. An uncut version for mature audiences and a version without sexual scenes for younger audiences.

Alternate Endings: There seem to be two endings, even for the 126 minute version. One version in which Steven (Hugo Stilitz character) wakes up after killing the shark in a hospital sans an arm, and another version that is more vague about what happens to him. In that ending, after it shows the tiger shark killed, the screen turns red as it surrounds the lamp/flashlight Steven had dropped and then fades out to a scene of Andres, Susan and Hugo posing in front of the camera, they kiss, then the screen fades to water and the directors name flashes on the screen.

The USA original release was heavily edited from the original 126-minute version which eliminates most of the opening sub-plots including Steven in a hospital bed in Houston after falling ill at work and his doctor advising a vacation, and Miguel first meeting and romancing Anita and the introduction of Kelly and Cynthia hitching a ride to Cancun in an orange truck and being attacked by the two occupants.
