In Martian Child, David Gordon (Cusack) is a successful science fiction author, plagued by both the death of his wife and writer's block. When a group home worker (Sophie Okonedo) tries to pair him with a young boy named Dennis (Bobby Coleman), David initially resists. But once David spends time with Dennis, he realizes how special the boy is. The outsider (and sci-fi fan) in David thinks he might just understand Dennis best since the child believes that he's from Mars and he'll return there soon. David and Dennis struggle to create the most unconventional of families, as Dennis strives to learn more about being human. Martian Child is a moving drama that works because of the genuine performances of everyone involved, but it rides on both the experienced shoulders of Cusack and those of his young co-star, Coleman. Both excel at communicating their characters' isolation and eventual connection, but it's Coleman's work in his first major role that is such a pleasant surprise. Supporting turns from Cusack's sister Joan (who plays his sister in the film) and Amanda Peet add emotional depth to the sweet story.
