It was recently announced that Bradley Cooper (The Hangover, Alias, Midnight Meat Train) will be headlining Relativity Media and Rogue Picture's thriller titled "Dark Fields". Cooper has replaced "Transformers" star Shia LaBeouf according to reports. The movie is based on a book of the same name by author Alan Glynn. Neil Burger will be directing the picture from a script written by Leslie Dixon (The Thomas Crown Affair). The premise is rather strange and I should be surprised that Bradley Cooper would headline a flick like this after moving to A-list status after the unexpected sucess of "The Hangover". Then again, he did star in "Midnight Meat Train" thus anything's possible. Read on to see what the movie is about.

Based on Alan Glynn's book, the story follows a down-and-out writer (Cooper) who gets his hands on a top-secret pharmaceutical drug that makes one smarter. He experiences sudden financial and social success but soon discovers that the drug has lethal and lasting side effects.

Before long, mysterious antagonists are pursuing him. Cooper replaces Shia LaBeouf who was originally attached to star.

We have no idea why LaBeouf backed out of the project, but we're assuming it involved scheduling conflicts with his other projects.
