Actor Michael Fassbender and screenwriter Ronan Bennett (Public Enemies) are teaming up for an untitled drama based on the legendary Celtic warrior Cuchulain.

The story will revolve around King Conchobar, and his Uliad Tribe's conflict with Queen Mebh's Conchatta Tribe. Michael Fassbender will play Cuchulain, Conchobar's nephew who possesses super-human fighting skills. The most famous of these tales is the Cattle Raid of Cooley, where Cuchulain managed to fend off an entire army sent to steal Conchobar's prized white bull.

Michael Fassbender and Ronan Bennett have raised developmental funds through Finn McCool Films, although no other studio is attached to the proejct. Both Michael Fassbender and Ronan Bennett originally hail from Northern Ireland.

No production schedule was set for this untitled Cuchulain project.
