Best movies adapted from a book.

[IkeaBoy]

I hate repeating things over and over again so I didn't see these mentioned (what everyone has said I pretty mcuh agree with). And personally I don't think plays should count unless it's a radical adaptation of it.

Wag the Dog- FAR better than American Hero, the book it was based on
Psycho- Psycho
O Brother Where Art Thou- The Odyssey
Clockwork Orange
