at Isla Mujeres, a resort island near Cancún. All the underwater scenes were filmed with live sharks using the submarine expertise of Ramón Bravo. Due to the censorship imposed by the Mexican government at the time, there were two versions of the film prepared - the so-called uncut version, with plenty of explicit nudity, for foreign markets, and a cut version for domestic (Mexican) exhibition. It's now possible to find both versions on DVD. The original English dub in theatres and on video featured the voices of Susan George and Fiona Lewis, who played the two British tourists in the film. However, this dub was later lost and a new one was created with American voice actresses, which is the one used on the DVD.
