Matt Damon has lined up another potential directing vehicle, setting up an untitled drama at Warner Bros. that he wrote with actor John Krasinski.

Krasinski also will star in the project, which is eying a spring start. The movie is said to be in the vein of Erin Brockovich, the 2000 legal drama that won Julia Roberts her best actress Oscar. While plot details remain scarce, the story centers on a salesman (Damon) who arrives in a small town only to have his life changed. The project will be produced under Krasinski’s Sunday Night banner. Damon and Chris Moore will also produce.

Krasinski came up with the idea for the script and developed the idea with author Dave Eggers. Krasinski then pitched the idea to Damon for the two to write and star.

Damon has been itching to find a directing vehicle and is working on a couple tracks. He last year set up Father Daughter Time: A Tale of Armed Robbery and Eskimo Kisses, a script by Matthew Aldrich. Warners is the home for that project.

It is unclear which project will go first, although some insiders say Damon will be in the helmer's chair with the untitled drama in the spring. He is juggling a schedule that includes Liberace, Steven Soderbergh's biopic of the flamboyant pianist for HBO Films, and another possible film role.
