Warner Bros. has hired Peter O’Brien (Halo: Reach) to write Todd Phillips' thriller Trust Your Eyes. The movie is based on the book written by Linwood Barclay. The story is a conspiracy thriller that's a cross between Alfred Hitchcock's Rear Window and Barry Levinson's Rain Man. It centers on "a schizophrenic, map-obsessed savant who witnesses a murder online on Manhattan's Lower East Side. He insists that his older brother investigate, and it's not long before the siblings cross paths with a politically-connected ex-cop and his ice pick-wielding henchwoman, who are themselves scrambling to clean up after a high-stakes screwup."
This could end up being a great film. Phillips is mostly known for making comedies like The Hangover, but I can see him branching out into different genres. He seems like the kind of filmmaker that has a wide range of talent. O'Brien is best known for writing the video game Halo: Reach, but has since worked on several screenplays for movies that have yet to be made.
Here's a description of the book:
A schizophrenic man spends his days and nights on a website called Whirl360, believing he’s employed by the CIA to store the details of every town and city in the world in his head. Then one day, he sees something that shouldn’t be there: a woman being murdered behind a window on a New York street. Suddenly Thomas has more to deal with than just his delusions, as he gets drawn into a deadly conspiracy.
