Marooned (1969)

There's a LOT of technobabble in this film. There are entire scenes consisting of people checking all the various equipment. Some of these scenes work, but others are painfully slow. This movie takes a long time to get going, but once it does, it's an entertaining space thriller. Gene Hackman is especially good as one of the marooned astronauts. The final 20 minutes or so are truly suspenseful (I kept yelling out loud at the screen) and are a mostly satisfying conclusion to the long build-up. 3 stars.
