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. ****
