Warner Bros. and Brett Ratner’s RatPac Entertainment have tapped Peter Straughan to adapt Donna Tartt’s Pulitzer Prize-winning novel “The Goldfinch.”

Straughan adapted John le Carre’s “Tinker, Tailor, Soldier, Spy.” Courtenay Valenti and Racheline Benveniste are overseeing for Warner Bros.

Nina Jacobson, Brad Simpson and Ratner are producing.

The book was published last fall and has been on the New York Times bestseller list for 39 weeks.

The story, which takes place over two decades, follows a 13-year-old boy who loses his mother in a bombing at the Metropolitan Museum of Art. He survives the explosion, steals the Carel Fabritius painting the Goldfinch, gets taken in by an Upper East Side family and eventually reunites with his father, an alcoholic gambling addict who takes him to Las Vegas.

Warner Bros. bought movie rights to Tartt’s first novel, muder mystery “The Secret History,” several years ago.

Straughan is repped by CAA and UK Agency Casarotto Ramsay & Associates. His attorney is Craig Emanuel.
