The Martian Child

I've altered my usual order here. After watching this DVD several times I finally figured out there was a book by the same title and borrowed it. 

Books and movies are two different mediums and it is not unusual for the movie based on a book to take inspiration from the book without following it closely. Since the book is told through the author's stream of consciousness it is obvious dialogue and plot had to be invented. Some items are retained:

Somewhere's name
The adoption of an abused, abandoned, hyperactive, disturbed 8-year-old boy who believes he's from Mars.

The DVD has a supplement that introduces the real Dennis. 

The movie within a movie that is Dracoban echoes the writer's distress at what the movie-making process has done to his text.
