It’s been more than 20 years since they last wrote a script together and Ben Affleck and Matt Damon are finally reuniting. The longtime friends are co-writing a story about two best friends who fight a duel to the death in a new film to be directed by Ridley Scott.

They will be working on the script for The Last Duel with Nicole Holofcener, based on the novel of the same name by Eric Jager.
