Warner Bros. is looking to acquire the rights to Donna Tartt’s Pulitzer Prize-winning novel “The Goldfinch”, Variety said.

However, sources close to Tartt say the author is still making a decision as to whether to move forward with an adaptation. Warners is the only studio that has shown interest in pursuing the bestseller as a movie project.

Nina Jacobson was originally attached as producer, but is no longer involved with the project.

Tartt and her team at ICM Partners have been very cautious about how they want the adaptation handled and whether the novel would work better as a film or miniseries.

The book was published last fall and still ranks second on the New York Times bestseller list.

The sprawling story, which takes place over two decades, follows a boy who loses his mother in a bombing at the Metropolitan Museum of Art. He survives the explosion and absconds with Fabritius’ painting, The Goldfinch. The story then follows him as a rich, Upper East Side family takes him in and he later reunites with his father — an alcoholic gambling addict who takes him to Las Vegas.

If a deal is made, Tartt and the studio will then look to find a screenwriter to adapt the property.
