It's impossible to deduce the psychology of Osama bin Laden from a list of movies at his compound, of course, and any of us subjected to evaluation based on our pop culture tastes might not hold up too well (I would hate for my A Walk to Remember DVD to fall into the CIA's hands). Nevertheless, this limited list contains a few interesting tidbits.
First, bin Laden clearly took an interest in himself -- it's probably smart to watch Where in the World Is Osama bin Laden if you're trying to, ya know, escape detection by the most advanced technology in armed history. Biographical accounts of his life also likely provided insight into how the West perceived him.
Second, what's with all the animated kids movies? Granted, Woody Allen's Antz is pretty dark, but Cars, Home on the Range, and Ice Age: Dawn of the Dinosaurs do not exactly fit the public image of a man conceiving the global terrorism plots. There were, however, several children in the compound, so it's reasonable to guess the kids movies were for them.
