Nacho Libre

Berated all his life by those around him, a monk follows his dream and dons a mask to moonlight as a Luchador (Mexican wrestler).
Nacho Libre is loosely based on the story of Fray Tormenta ("Friar Storm"), aka Rev. Sergio Gutierrez Benitez, a real-life Mexican Catholic priest who had a 23-year career as a masked luchador. He competed in order to support the orphanage he directed.
