Will Ferrell is the "Muhammad Ali of improv."

The comedian stars in Matt Piedmont's Casa de mi Padre, a Spanish language Mexican telenovela, and although the motion picture was a huge challenge for Will, the director says he rose to the occasion beautifully.

"For Will it was surely a Heart of Darkness in that he pulled off something almost impossible that surely caused him night sweats: having to act in a very specific Northern Mexican accent in a language he does not speak. He is the Muhammad Ali of improv and we tied one hand behind his back and threw him to the lions covered in barbeque sauce. For me it was pure joy and a grand psychedelic trip down a crazy rabbit hole, like being strapped to a rocket ship of love made of liquid lightning."

Will stars as the brother who must save his family's ranch from an evil, cigarette-smoking drug lord (Gael Garcia Bernal), and rescue his brother (Diego Luna) from a life of crime and Matt revealed he was delighted his feature film directorial debut was an R rated Spanish language satire.

"The script was amazing and had everything. The fact that was in Spanish only sealed the deal for me. You only get one first feature, and I'm thrilled mine is a Spanish language satire rated R for 'sexual content, drug use and bloody violence' as stated by the MPAA [Motion Picture Association of America]. They can't take that away from me," he said.
