The Mule (Spanish: La mula) is a 2013 film based on the novel by Juan Eslava Galán of the same name, starring Mario Casas and María Valverde alongside Secun de la Rosa. An infamous litigation about its finances erupted in the last days of shooting in October 2009, pitting British director, co-writer, and producer Michael Radford against Spanish producer Alejandra Frade. A theatrical cut, with Radford having cut ties to it, was eventually released in 2013.
