Deep Shock

Originally the eels in the film were going to be created by the American CGI team, and looked similar to a giant moray eel with a more sinister grin. But to save money, the American eel was scrapped, and the work was handed to the Bulgarian CGI team.

When a torpedo is launched, the head of the Hubris science complex, who is addressed as "Commander" (a naval rank) informs the United Nations Command Center buy saying, "Bird away." Torpedoes are always referred by the slang term "fish" by naval personnel, while non-naval military personnel refer to guided missiles by the slang term "bird."
