The Groundstar Conspiracy is your average spy thriller with George Peppard as the ruthless investigator from an unnamed government agency and Michael Sarrazin as a scientist who is the only survivor of a lab explosion at a top secret US space program called Groundstar. Peppard knows that Sarrazin is not who he says he is. But how did he get clearance in the place, what may or may not have been taken from the lab that the explosion covered up are the questions Peppard has answers for. Because Sarrazin's memory has been wiped clean.The key character in The Groundstar Conspiracy is Peppard as a ruthless government investigator, a man who could be J. Edgar Hoover if given half a chance. That title phrase comes from Peppard's mouth who would like to bug every bedroom in the country for security's sake, better to ferret out would be subversives.Of course Peppard plugs up his security leak, but Sarrazin, freedom, and Sarrazin's freedom pay a price.The Groundstar Conspiracy has some interesting notions to put forth, but the productions values are pretty skimpy. Christine Belford as a woman that Peppard's using to keep tabs on Sarrazin has her role very poorly defined. The players do their best, but the film's general mediocrity weighs heavily on their work.

This is a movie as easy to watch as to forget but it's quite entertaining.The story is very far-fetched,but in this kind of spy thriller including amnesia ,mysterious conspiracies and who-the-Hell am I? subject,it's the rule of the game.George Peppard tries hard to be evil but he does not always succeed;Michael Sarrazin is the perfect victim/culprit (God only knows) .The love story may seem derivative and it is,but there are enough unexpected twists to sustain interest throughout.The working title ("the plastic man" ) was perhaps a better choice than "The Groundstar Conspiracy "but it might have been a spoiler.

There are not too many spy films which can conjure up a team of excellent actors for a movie. This however is one. "The Groundstar Conspiracy" is a dramatic thriller of sorts, except that in this movie, the private company is the target not the country. An explosion in a top secret installation causes a great deal of damage and sets off an investigation to find out who was behind the espionage. Enormous amount of destruction to be sure, but what the chief investigator (George Peppard) Tuxan wants to know is who is behind the sabotage. His only clue is in the form of a single survivor named John Welles (Michael Sarrazin) AKA Peter Bellamy, a man who has no memory of what happened. This is an excellent vehicle for the Cat and Mouse game which follows. The survivor is having tremendous difficulty trying to remember who he is or was and Tuxan is allowing him to struggle while he watches out for any of his friends to come and help him recover. It's an excellent film and one which gives the audience just enough information to follow the hero to the surprising ending. A good film and one which is enhanced by Nicole Devon as Christine Belford and Cliff Potts who plays Carl Mosely. ****

Just re-saw The Groundstar Conspiracy after some 20 something years. Always been a big fan of both George Peppard and Micheal Sarrazin, so I was looking forward to this flick. Somewhat out-dated today, but for 1972, it wasn't all that bad. There are twists and turns. Plots and subplots. Action, suspense, drama, and even a little romance thrown in. Humor, at least a few lines, would of helped a lot here. There is a nice surprise sort of ending. Clearly this is not a masterpiece of a cold war thriller like The Spy Who Can In From The Cold or The Ipcress File, but The Goundstar Conspiracy is a nice little entertaining film. George Peppard looked great here and Micheal Sarrazin was in his prime. It's not their best roles, but if you're a fan. it's a good way to spend a rainy night.
