Scarlett Johansson will finally start production on her directorial debut next year (14) when she turns a Truman Capote novel into a movie.

The actress signed on to direct Summer Crossing in 2011, and promptly began working on adapting the story for the big screen.

The script is now complete and the project is currently being sold at the Cannes Film Market.

Johansson says, "Several years ago I began working alongside the Capote estate and writer Tristine Skylar to adapt Summer Crossing, an inspired early work of Truman's which has long captured my heart. Being able to bring this story to the screen as my full-length directorial debut is a life dream and deep privilege."
