Did You Know?


Writer Lewis Abernathy sold his script at the same time that friend James Cameron was working on his own "underwater monster saga". Despite Cameron's asking that he delay this movie to avoid competing with The Abyss (1989), Abernathy went ahead and was thereby deemed persona non grata with Cameron and associates until they patched together their friendship when Abernathy accompanied Cameron on the September 1995 filming of the wreck of the Titanic for Titanic (1997) (but not any actual dives to the wreck itself).

good effects, good cast, good film
22 April 2003 | by (Ipswich, England) – See all my reviews

Deep in the ocean some foolish marine biologists accidently disturb an ancient prehistoric creature from its slumber. The creature is understandably a little cheesed off and proceeds to cause the death of many of said biologists. With your brain safely checked in with the cloakroom attendant this film is undemanding and fun. The creature is particularly impressive and credit must go to the the special effects guys. The cast is eclectic and low budget with Miguel Ferrer giving the best performance as Snyder, the only member of crew realizing the gravity of their situation and slowly going stir crazy. This film is better than many other watery efforts and this includes bigger budget efforts like Leviathan and Sphere.
