Movie Review: ***^Capricorn One (1977)

This is a movie that leaves you unsettled.  There is a problem with the life dome for a Mars mission.  However, rather than scrub the mission, the leaders of NASA decide to fake the mission.  Dr. Kelloway (Hal Holbrook) explains they need to agree to cooperate to assure the safety of their families.  All is going well.  They have faked the mission for almost a year.  Upon re entry, the heat shields of the unmanned spacecraft fail.  Now NASA has a problem; three live astronauts (James Brolin, O.J. Simpson and Sam Waterston) who should be dead.  It doesn't take long for them to figure out the puzzle.  They escape, and take off first in a jet, then on foot in a desert.  NASA finds two of the astronauts, and we assume they are murdered.  Only one is alive, but sure to be captured.  There is a reporter (Elliott Gould) on the case who is unravelling the plot.
