Capricorn One (1977)

A late 70s conspiracy thriller set around NASA's faking a manned mission to Mars. The three crew members of the Apollo 11 Capricorn One module aren't happy with the situation, but what can they do? The world is watching.
Dir. Hyams makes good use of his 2.35 frame and the now-familiar mission control setting lends believability to the scenario. I'm not sure why it's considered such a classic of the genre by some folks, but it's certainly an entertaining ride for as long as it lasts.
