David Gordon is a successful science fiction author. Two years after the death of his wife he is suddenly considering opening his life up to another person by adopting a young boy—a troubled orphan named Dennis. The problem? Dennis seems convinced that he isn’t human. Instead, he’s visiting Earth on a mission from Mars. Martian Child explores the struggles that David and Dennis have as they learn to love and trust each other on their way to becoming a family.

Based on an award-winning novella, Martian Child is purely character-driven drama. Given the nature of the project, casting is absolutely critical, especially for the key role of the young boy, Dennis. The good news is that a solid line-up of talent is on hand. The always entertaining John Cusack plays David Gordon with his usual good-natured style. Dennis is played by Bobby Coleman, who at his tender age is already well on his way to being a veteran in the film business. Amanda Peet appears as friend and apparent love interest Harlee. Sister Joan Cusack and Oliver Platt also appear in supporting roles.

As good as the talent on tap may be, the story in Martian Child doesn’t fare nearly as well. It’s at its best in the early going when the relationship between David and Dennis is being established. The quirky behavior exhibited by Dennis provides ample opportunity for light laughter and it’s easy to get drawn in to this heartwarming story. As the action progresses, though, things get a little disjointed and the pace begins to suffer. Several subplots, such as a burgeoning romance between David and Harlee, try to provide additional dimensions to the film but wind up going nowhere.

Still, if you enjoy seeing the Cusack siblings on the silver screen you’ll probably find something to like about this film. Despite the film’s shortcomings, I still walked out of the theater having enjoyed the journey. On the other hand, you won’t be missing out on much if you elect to wait for the inevitable DVD release in the not-too-distant future.

Martian Child is rated PG for “thematic elements and mild language.” I don’t think that most audiences would find anything terribly offensive here.
