When Ethel and Mr. Grant meet in the roadhouse, the exterior sign says "Jefty's Roadhouse"-- a stock shot from Road House (1948) with Richard Widmark as "Jefty". See more »


While discussing their "scientific" dilemma, Dr. Stevens and Prof. King assert that "heavy water" is found naturally in the depths off the coast. "Heavy water" is deuterium oxide and does not occur naturally, and is water enriched with the hydrogen isotope deuterium, not the result of water under pressure as our two scientists suggest.

[first lines]
William S. 'Bill' Grant: Don't touch that.
[Grant shows his credentials]
Ted Baxter: William S. Grant, Special Investigator. Department of Defense, Washington. Well, I guess that makes it pretty official.
William S. 'Bill' Grant: Yes, I guess it does.
Ted Baxter: His body's rigid with burns. The boat's charred too. Yet, there's no sign of fire. We better get him out of the water.
William S. 'Bill' Grant: I'll take care of him myself.
Ted Baxter: I just though I'd give you some help.

User Reviews

Recommended Mostly to 1950s Sci-Fi Completists
5 July 2003 | by Space_MafuneSee all my reviews

While this Science fiction story lacks any real sense of credibility and our monster-The Phantom disappoints due to a lack of action and a rather plain appearance, there's enough inherent strangeness and weirdness going on here to make this an intriguing watch to fans of cult movies - the science fiction variety. Seeing Kent Taylor and Philip Pine is a treat here as always and they , along with Cathy Downs and Michael Whelan do give competent performances. Recommended mainly to those with a lot of patience and a love for Grade-Z movies.
