The story of a man becoming a father...and a boy becoming a son...

Based on an award-winning short story by sci-fi luminary David Gerrold, Martian Child sees John Cusack as a recently widowed science fiction writer who forms an unlikely family with a close friend (Amanda Peet) and a young boy he adopts who claims to be from Mars. The new couple ignore some sage parenting advice from the widower's sister (Joan Cusack) and get more than they bargained for when a series of strange occurrences lead them to believe that the child's claim may be true!
