Julie Blair (Anne Kimbell) is an American vacationing at a sea-side village in Mexico. She hears stories about a man-eating creature dwelling in the cove.
This film is a low budget science fiction film in every sense of the term low budget. Director Wyott Ordung (1922–2005) doubled as an actor (playing Pablo), and this was his first of only two times in the director's chair. In fact, his only real experience before this was a writer on another low budget flick, "Robot Monster".
Most notable is the producing credit of Roger Corman, who took a modest $30,000 budget and earned more than ten times that back at the box office. No small feat, especially from someone just starting out in the business. This also marks a collaboration between Corman and cinematographer Floyd Crosby; Crosby had been making films over twenty years, but would be possibly best known later on for shooting Corman's finest films.
This was also the debut of Jonathan Haze, a gas station attendant that filled the small role of Joe. He must have done something right, because Corman hired him for numerous productions over the next decade, including the starring role of Seymour in "Little Shop of Horrors".
As for the film itself, there are things to like and things that could have been improved. The monster is actually rather cool looking, and when revealed is no disappointment. To use him sparingly, they also have a shark and an octopus, which may cause a few people to jump. The film is also rather short -- only 64 minutes -- so there is little time for the pace to slow down. Variety praised the film, calling it an "oddity" but "well-done", noting that "Corman's production supervision has packed the footage with commercial values without going overboard."
The negatives are few, but worth pointing out. The forced romance was a bad idea, though probably almost necessary for a film of its day. This is somewhat compensated for by having the main character be a heroine rather than a hero -- not the strongest female lead, but a female lead nonetheless. The biggest issue is the sound. Clearly they had not invested in a boom mike, because scenes were either overdubbed, or the conversations were drowned out by the ocean waves...
While not the best film of 1954, it has its historical merits and is fun in its own way. For a low budget film now sixty years old, I think it holds up respectably well.
