The movie - "Nacho Libre," starring Jack Black as a Mexican wrestler.
Best. Idea. Ever.
Apparently, the movie was written by a team consisting of the writers from School of Rock as well as Napoleon Dynamite (Jared Hess, Jerusha Hess, and Mike White), and was directed by Jared Hess.
Jack Black stars as Ignacio (friends call him Nacho), a Mexican priest who moonlights as a lucha libre wrestler to raise money for his orphanage in this comedy from the creators of "Napoleon Dynamite" and the writer and star of "The School of Rock."
