Matt Damon was planning to make his directorial debut on an as-yet-untitled drama starring himself and John Krasinski, but now Damon's stepping aside to let his "Good Will Hunting" director Gus Van Sant take the reins. 

Based on an idea by Krasinski and his "Away We Go" collaborator Dave Eggers ("Where the Wild Things Are"), the film centers on a big time salesman (Damon) who begins to question his life choices after arriving in a small town. Krasinski will play a corporate rival. 

Deadline reports that Chris Moore will produce the film, which is aiming to start shooting in April, likely in upstate New York.

In addition to the Oscar winner "Hunting," Van Sant and Damon teamed for 2002's "Gerry," co-starring Casey Affleck.
