Matt Damon will make his directorial movie debut with a small-town drama.

The 'Cantagion' actor and John Krasinski have teamed up to write The Script for the as-yet-untitled movie, which they will both also star in.

The film tells the story of a salesman, played by Damon, who arrives in a small town and has his entire life turned upside down. It is not yet known who Krasinski will play.

'The Office' star Krasinski came up with the idea for the plot and they then pitched the idea to Damon and they began working on the script.

They have now taken it to Warner Bros. and while the studio hasn't yet given it the go-ahead, it is thought it will soon.

Damon has been looking for a directorial project for a while and has also signed up for 'Father Daughter Time: A Tale of Armed Robbery and Eskimo Kisses'. However, it is thought he will helm the Krasinski drama first.
