Joel and Ethan Coen will write and possibly direct an adaptation of Ross MacDonald’s bestselling novel “Black Money” for Warner Bros., sources have confirmed to Variety.

Joel Silver is on board to produce and co-finance the film with Warner Bros. via Silver Pictures Entertainment. Steve White will exec produce.

The story follows a private eye who’s hired by a betrayed lover to expose the man who ran off with his girlfriend, only to discover a major conspiracy at the root of the case. MacDonald wrote the novel in 1966 and died in 1983.

The film fits into the Coens’ wheelhouse of noir films, which include “Barton Fink,” “Fargo” and “Blood Simple.”

The Coen brothers most recently wrapped production on Universal’s “Hail Caesar!” with a cast that includes George Clooney, Channing Tatum, Scarlett Johansson and Jonah Hill.

Silver next project that he is producing is “The Nice Guys” for Warner Bros. The film stars Ryan Gosling, Russell Crowe, Matt Bomer, Kim Basinger and Keith David with Shane Black directing.

They are repped by UTA. The news was first reported by Deadline Hollywood.
