My review was written in May 1986 after watching the movie on Lightning video cassette.
"The Sea Serpent" is a low-grade Spanish monster picture shot in 1984 in Portugal and Spain. Entry is aimed at youngsters who like watching miniatures (here in the form of boats, train, helicopter, lighthouse, bridge and monastery) and went directly to video cassette release Stateside.
Timothy Bottoms portrays Capt. Barrios, a seafarer given a second chance after an accusation of being drunk on a disastrous earlier voyage wherein the brother of Lenares (Jared Martin) was lost at sea.
In a prologue, a U. S. bomber in trouble drops an A-bomb in the sea, exploding it (stock footage of a mushroom cloud) so s to avoid the sophisticated weapon being retrieved by a nearby Russian boat. The explosion awakens a sea monster on the ocean floor, and said monster proceeds to destroy Barrios' ship.
At a naval hearing, disgruntled Lenares testifies that Barrios was drunk at watch again, and no one believes the captain's tale about a sea serpent. Stripped of his captain's license and subject to criminal proceedings, Barrios leaves Spain and heads for isbon after reading a newspaper story about a woman who reported seeing a sea monster there.
He finds her (Taryn Power) in a hospital and breaks her out, the tow of them traveling to a university to consult Prof. Wallace (Ray Milangd, in his final feature film) about the monster's legend.
After having seen the monster himself, Lenares turns over a new leaf and joins up with the heroes, the four of them going hunting. They singe the beastie when an oil car of a passing train falls on it and explodes, with the monster swimming away towards Africa, setting up (horror of horrors) the prospects of a sequel.
Since the monster is alternately hand puppet or a full-view Venus Flytrap-styled mouth for chewing hapless cast members, picture is obviously for smallfry only. Articulating in English but crudely dubbed, cast is bland and tech credits weak.
