Robert A. Heinlein's 1951 novel The Puppet Masters comes to the screen 43 years later. Sharp-eyed viewers will recognize similarities to Invasion of the Body Snatchers, but Heinlein's book came first. Parasitic space aliens invade the Midwest, taking over the bodies of humans and manipulating these unfortunates to do their bidding. US security agent Donald Sutherland and his team of troubleshooters attempt to squash the extraterrestrial scheme before everyone in the world is turned into Howdy Doody. Adding an extra layer to this familiar scenario is the fact that Sutherland doesn't get along with everyone on his side-in particular, he has a lot of trouble relating with his son Eric Thal. Stuart Ormes' perfunctory direction is not up to the standard set by the actors and special effects.
