"Classic conspiracy movie from 1978 about the first manned mission to Mars. All appears to be going well until the astronauts are pulled off the ship just before launch by shadowy government types and whisked off to a film studio in the desert. It transpires that the space vehicle has a major defect which NASA just daren't admit. At the studio, over a course of months, the astronauts are forced to act out the journey and the landing to trick the world into believing they have made the trip."
