EXCLUSIVE: Peter O’Brien has just been hired by Warner Bros to adapt Trust Your Eyes, the Linwood Barclay novel that Todd Phillips is attached to direct. Phillips and his Green Hat Films banner are producing with Dan Lin.

The book is a Rear Window-style paranoid thriller. A map-obsessed schizophrenic savant witnesses a murder in New York through a computer map program, and then convinces his brother to investigate. These impulses never end well, and the siblings find themselves smack in the center of a deadly political conspiracy. It is the first thriller for The Hangover helmer. Jon Silk co-producing and Barclay and Scott Budnick and Mark O’Connor exec producing.

O’Brien has been busy at Warner Bros, recently rewriting Line Of Sight with Act of Valor‘s Mike McCoy directing. O’Brien’s original script Unlocked, which made the Black List, was bought as a spec by the studio. That one is about a female CIA interrogator who becomes unwittingly involved in a devastating biological attack on London after she’s tricked into allowing a terrorist to divulge information to his cohorts. That script got O’Brien hired at Paramount adapting the Robert Ludlum thriller The Chancellor Manuscript, which Marc Forster will direct. It also got him the Fox 2000 thriller The Jury, based on the British miniseries. O’Brien also wrote the story for the video game Halo: Reach. Original Artists and Brillstein rep O’Brien.
