The movie just goes to show cheap doesn't necessarily mean bad. It's a poverty row PRC production. But the movie also has a fine cast, distinguished direction, and expert craftsmanship. On the other hand, the story tends to convolute, and we never do find out the exact nature of the "strange illusion" that anticipates real events. But then an occult touch lends the movie a mysterious nature beyond the who killed young Paul's (Lydon} father. And that opening sequence, apparently filmed through a gauzy filter, remains a real grabber.
Lydon's simply excellent in the pivotal role. Hard to believe he was only twenty at the time since he's so well poised. His teen friends are a lively bunch, showing what teen behavior and slang was like even in those war years. (See if you agree: Jayne Hazard (sister, Dorothy) looks like a fresh-faced young Marilyn Monroe.) But the real grabber is Warren William. What a creepy character his Curtis is, seeing his face light up whenever he spies a nubile young thing like Lydia (McLeod). Actually, having a near-pedophile as a character is a pretty daring move for the time. And William transitions so smoothly from the masterful to the lustful that he steals the film from heavy competition. Too bad this distinctive performer is largely forgotten. He's definitely among the rewards of watching old movies.
Anyhow, cult director Ulmer again shows how to shape difficult material into an intriguing final product, despite budgetary drawbacks.
