I think that the film gives a real life story of autism that you might not get from the book. The book is good at explaining how good autistic kid is at writing a book and shows how their minds work. In the movie it shows how Henry goes into his own world just like Christopher does when he is on the train to his mother's house. I believe that Henry is very much like Chris, they both go into their own worlds, they are very knowledgeable about certain things, they do not like a lot of people in one area at one time. Both boys are in special classes but they are very knowledgeable to be in regular classes but their schools will not let them be with normal kids. Autistic kids have a very good memory at times, for example in the book Chris is out in the country with his family for the weekend and he counts how many cows he sees and how many miles it is from town to town. In the book he can remember the date of when they went out into the countryside.
