Oscar Isaac will be a dangerously partisan father in his next film.

The 33-year-old Guatemalan-born actor of Cuban and Guatemalan descent, the star of the upcoming Joel and Ethan Coen-directed Inside Llewyn Davis, has been cast in the indie film Partisan.

Written and directed by Ariel Kleiman, the film is described as a confronting fable about a vengeful man raising his children to attack the world that wronged him.

Isaac’s credits include The Nativity Story, Drive, Sucker Punch, W.E. and The Bourne Legacy.
