MIAMI (AP) - Diego Luna and Gael Garcia Bernal once again share credits in the big screen, this time as a pair of rival drug dealers in "Casa De Mi Padre," a comedy starring Hollywood supstar Will Ferrell, spoken completely in Spanish and opening this week, March 16, in the U.S.

In this western satire directed by Matt Piedmont, to be shown with English subtitles, Ferrell portrays Armando, a cowboy who has worked and lived his entire life in Mexico in his father's ranch (played by the late Pedro Armendariz Jr. in one of his last roles), and whom he despises and minimizes against his brother Raul (Luna), who arrives with his fiancée Sonia (played by the daughter of "El Puma" Jose Luis Rodriguez, Genesis Rodriguez) to save the ranch from bankruptcy.

Raul turns out to be a renowned drug dealer who ends up facing the Onza (Gael Garcia), the most important drug dealer in the area. The story complicates even more when Armando falls madly in love with Sonia causing a confrontation between brothers.

"The support I got to be able to speak Spanish was fantastic," said Ferrell recently, in English, during a friendly soccer match between the Colombian and Mexican national teams at the Sun Life Stadium in Miami, where the main actors were also present promoting the film.

The comedian, who doesn't speak Spanish and who learned his lines phonetically, had to practice very hard to bring the project forward. In fact, he acknowledged that the only word he remembered in Spanish was "Chicharito", an allusion to Mexican soccer player Javier Hernandez, nicknamed this way.

He also highlighted the performance of his Hispanic colleagues and said that working with them was very significant and rewarding.

And it's just that despite Ferrell's accent, his Spanish is very convincing and with this they achieved one of the main goals.

"Working in Spanish, for starters, is already crazy," said Luna to the AP in a recent interview. "Even though he (Ferrell) didn't want the only funny thing about the movie to be him trying to speak Spanish, it is very fun and worthwhile. This, mixed with the different situations and the story itself, make this a unique project."

For this Mexican actor, one of the most interesting aspects is to see who is behind the project.

"It wasn't something that occurred to us in Mexico and we came looking for Will to do it. It's the other way around. This is a project that occurred to him and his crew, they wrote this movie where they make this series of comments and they invited us to be part of it," he said.

He also praised the use of satire to make political and social commentary, and about the stigma and perception in the United States about Mexico and vice versa.

"I liked the possibility of making a movie so irreverent in so many ways. Besides, it doesn't look like anything done in this or other countries. As a challenge, it attracted me very much," said Luna, adding that when he read the script (by Andrew Steele) he felt identified with elements that seemed very attractive, which convinced him to participate in what he considered a high-risk job. "As an actor, you rarely get this chance."

He said he was aware that "Casa De Mi Padre" could be controversial for its concept, content and theme, but he assured that there is no better way of criticizing delicate issues like drug dealing and violence than through comedy.

"These are issues we can't ignore. I think that on the contrary, we should talk about this as much as we can. " he said. "That's why I was interested in making this movie, because I think the debate it can generate here in the United States is important."
