Following a number of short, mini-teaser trailers for Casa de Mi padre, the first full-length trailer has finally arrived. The movie, entirely in Spanish, stars Will Ferrell as a Mexican rancher who must save his family’s farm while defeating a notorious drug lord and winning the hand of the lovely Sonia. This trailer is absolutely ridiculous, and that’s a very, very good thing. Ferrell is at his most goofy here, and the film looks to be a laugh riot. The supporting cast is surprisingly fantastic (Gael Garcia Bernal, Diego Luna) and a swell appearance by Parks and Recreation’s Nick Offerman as the American in the film put a big smile on my face.

Hit the jump to watch the trailer. Casa de Mi Padre opens March 16th.

Here’s the official synopsis for Casa de mi Padre:

Armando Alvarez (Will Ferrell) has lived and worked on his father’s ranch in Mexico his entire life. As the ranch encounters financial difficulties, Armando’s younger brother Raul (Diego Luna) shows up with his new fiancée, Sonia (Genesis Rodriguez). It seems that Raul’s success as an international businessman means the ranch’s troubles are over as he pledges to settle all debts his father has incurred. But when Armando falls for Sonia, and Raul’s business dealings turn out to be less than legit, all hell breaks loose as they find themselves in a war with Mexico’s most feared drug lord, the mighty Onza (Gael Garcia Bernal).
