George Clooney and Grant Heslov picked up John Grisham's novel, The Innocent Man: Murder and Injustice in a Small Town for Warner Independent Pictures and their Smoke House Productions.

The book, published in October, is the true story of a gross miscarriage of justice that sent Ron Williamson to Oklahoma's death row for 11 years for a murder he did not commit, reports Variety. Among the flimsy evidence: eyewitness testimony from the man ultimately convicted of the murder.

No production schedule has been set for The Innocent Man: Murder and Injustice in a Small Town.
