Watched Capricorn One last night (another birthday DVD from Rachel). I've seen it so many times and is possibly one of my favourite films of all time!
The film centres around what is supposed to be the first manned mission to Mars. But it quickly emerges that due to technical and political reasons the mission needs to be abandoned. Or rather, the mission goes ahead, it's just that the astronauts are removed from the rocket before it launches. What follows is an attempt to fake the Mars landing, and in my opinion it makes for a great thriller even though it is now over 30 years old!
Seems all the more appropriate due to the 40th anniversary of the first lunar landings, given the movie was inspired by the claims that the moon landings were faked.
IMDB seems to suggest that a remake of teh film is due out next year.
