The movie was released on November 2, 2007.
Tropes for the film:
- Ambiguous Disorder: The title character is a young boy who doesn't understand facial expressions (he takes pictures of other people's facial expressions to try and puzzle them out of his leisure) and has multiple sensory issues (he wears a weight belt all the time to keep from "floating away", is overly fond of seat belts, and can't stand sunlight). He also displays signs of having Synesthesia.
- Daydream Believer: The film has a dark spin on this; the eponymous kid is a a Daydream Believer as a coping mechanism for his social awkwardness. It chronicles his adoptive father's struggles with the son's delusion that he's really from Mars and his "real parents" will come pick him up any day now.
- Department of Child Disservices: Social Services seriously considers taking Dennis away from what is probably the first supportive adult influence he's had in his entire life. Their reasoning? He's taking more than a month or two to just get over his social awkwardness and the extraordinary coping methods he developed to deal with severe abuse and neglect.
- The Film of the Book: The movie is based on David Gerrold's 1994 book of the same name.
