Capricorn One
Thanks to repeated showings on cable television and home video, this speculative thriller has built quite a loyal following since its release in 1978. The provocative "what if?" scenario still packs a punch, even if it is not always believable. James Brolin, Sam Waterston, and O.J. Simpson star as three astronauts who agree to spare the government embarrassment by faking their historic landing on Mars after their spacecraft is determined to be unsafe for blastoff.
