Harris directed and starred in Pollock (2000) with great success, so he's decided to do it again. He has chosen to not only direct and star in Appaloosa, but he is also writing the screenplay. The film is based on Robert B. Parker's novel about a marshal in a High Noon scenario with a corrupt rancher. Also attached to the project is Diane Lane and Harris' co-star from History of Violence, Viggo Mortensen (you can check out Karina's review here).
There aren't many production details yet as Harris is still busy promoting the upcoming film Copying Beethoven (directed by Agnieszka Holland), where he plays the famed composer in his later years. Like I said, the man has range.
