A good story, a little tepid, but with a nice twist at the end. Kerwin Matthews (the best Sinbad), Ray Danton (Legs Diamond), and Julie Adams (Creature from the Black Lagoon) don't exactly form a triangle. Matthews gets to display the anger missing from his fantasy roles, Danton makes a complex bad guy, and Adams is gorgeous and sincere, a 50's version of Jennifer Conelly. Screenplay has some good lines (but not enough) by Richard Alan Simmons who wrote Incredible Shrinking Man (but not its story). If you like the actors, worth checking out.
