Hollywood loves using books as source material - this year's Best Picture category at the Oscars features "Life of Pi," "Lincoln," "Argo," "Silver Linings Playbook," and "Les Misérables," all of which began as books.

But did you know that Oscar winner "Million Dollar Baby" began as a series of short stories written by a boxing trainer who went by the pen-name F.X. Toole? Or that "Shawshank Redemption" and "Stand By Me" were both originally Stephen King novellas in the same collection?
