Capricorn One is a movie I truly love. Not even OJ's subsequent fall from grace can make me love it any less.
I saw the movie in a theater when it was first released. The audience really got into it -- gasping, applauding, booing, laughing, cheering, etc. This actually added to my enjoyment! I've watched the movie many times since then, and I've loved it each time.
I take Capricorn One for what it is: an entertaining, well-made thriller with great performances all around. Even when I know what's going to happen, the movie immediately grabs hold of me and doesn't let go. Others have pointed out inconsistencies, technical errors, plot holes and so forth, but these things don't bother me. I want to go on a disbelief-suspended wild ride, not pick everything apart.
As one of the astronauts, Sam Waterston is a hoot! He supplies some wonderful comic relief, as does Telly Savalas. And Jerry Goldsmith really outdoes himself with the score.
As a matter of possible interest, when Caulfield loses control of his car the driving is done by Bill Hickman, who also did the chase scene in The French Connection and drove the Dodge Charger in the chase scene in Bullitt.
I won't put down anyone who doesn't like Capricorn One. If we all felt the same way about everything, life could get pretty boring. For those who think anyone who enjoyed the movie is an idiot, then I'm happy to be an idiot.
