The comic drama “Martian Child” stars John Cusack as a recently widowed science fiction writer who adopts a young boy that claims to be from Mars. But the new father ignores some sage advice about the perils of parenthood from his sister and gets more than he bargained for when a series of strange occurences lead him to believe the child’s claim may be true. Based on an award-winning short story by sci-fi luminary David Gerrold, “Martian Child” is directed by Menno Meyjes (Oscar nominated screenwriter of “The Color Purple”) and co-stars Amanda Peet and Joan Cusack.
