Scarlett Johansson is set to step behind the camera for the first time to direct Summer Crossing, an adaptation of Truman Capote's first novel.

The Avengers star will make her directorial debut with the film, which is set in the summer of 1945 and is about a 17-year-old girl who decides not to go on holidays to Paris with her parents so she can spend the summer with her Jewish valet parking attendant boyfriend.

Johansson said of the project: "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."

The book was unpublished until 2005, although it was written by Capote in the 1940s. Capote is thought to have discarded the manuscript because he wasn't satisfied with it. The book was later salvaged from a bin by a janitor at a New York apartment the writer briefly stayed in.

Following the janitor's death, his nephew discovered the work, resulting in it bring published posthumously, 21 years after the writer's death.

The film on Summer Crossing is expected to begin next year.
