These days, there are very different ways off acquiring knowledge. Films, books, revues, magazines, movies, etc. Surprisingly enough, most of the films our days are take from books. They are modernized and cut down the most important parts.
             If we compare the film "Igby goes down" with J.D Salinger's "The Catcher in the Rye", we might find the characters of one represented as similar yet different in the other one. At closer comparison, one can see that many characters are similar, even though the different character traits of one figure in the novel might each be represented by a single figure in the film but, the resemblance is nonetheless still very noticeable.
             Holden is represented mostly by Igby. For example, in the novel, Holden has the tendency of lying in many different circumstances, just like Igby in the film. Another factor that appears in both, the novel and the film, is that both, Igby and Holden had been abused in one way or the other. Holden has been abused many times by teachers from school. Holden says so himself after the awkward experience he had at Mr. Antolini's place, on page 193:
             ... When something perverty like that happens, I start sweating like a bastard. That kind of stuff's happened to me about twenty times since I was a kid. I can't stand it.
             Igby on his side did not get sexually abused, yet got physically and mentally brutalized by his godfather DH. It happened the first time, when he walked in on him and Rachel, and saw his godfather, sitting there, his legs wide open and his pants down. Then later on in the film DH beat him for having messed up his affair.
             Another important similarity exists in the fact that both Holden and Igby feel let down by their friends. In the case of the film, Igby does not only feel that way, he is let down by his friend Suki. She claims several times throughout the film to be Igby's best friends, and to always be there ...
