A poster child for cheesy 50s sci-fi. The special effects are horrendous, the little science lessons hopelessly outdated and the sci-fi bits are kept until the very end. There is something pleasantly uncomplicated about a film like this though, and the cheese is more than cheesy enough to carry at least some appeal.
A young boy looks out his window at night and sees an unidentified object crashing nearby. His dad goes out to take a look and doesn't come back until the next morning, a changed man. The boy believes that something has taken over his dad, but nobody wants to believe him. Until he meets a nice lady at the police office.
The middle part of the film is fairly long and uneventful, which is a tad odd as the sci-fi elements looked very practical and not at all expensive to pull off. The aliens are basically just people in an ugly tracksuit wearing masks. But once the film gets up to speed there's some fun to be had. Not what I'd call good cinema, but not terrible to sit through either.
