Breaking Bad - Giancarlo Esposito talks season 4 Finale & Revolution

ENTERTAINMENT WEEKLY: What do you remember about shooting “Hermanos”? GIANCARLO ESPOSITO: I was about to be with Spanish speakers who were all fluent in Spanish. I didn’t want to be the weak link in the scene in terms of the language, so I really buckled down to learn the language…. It’s not typical Spanish. It’s Chilean Spanish. And we had a Puerto Rican speaker. We had a Spanish speaker from Spain. All of them had different ways of saying the same thing. But thank goodness I take what I do seriously and really love it. I wanted not to offend any Chilean Spanish speakers. [Laughs]

What I didn’t count on was being so committed to Gus’s emotional state. I’d been playing Gus for a little while and had committed myself to dropping my energy to a point where I could be a real listener and observer of people. This episode takes us back 20 years, and we’re around the pool where Gus is with his nemesis Don Eladio (Steven Bauer), who he absolutely hates because the guy is a disgusting slob and doesn’t really know how to grow a business. Gus has great dreams and a great imagination in terms of how to start his chicken business and have it be a front for the meth business. And as he explained it to Don Eladio with his protégé Max, the air gets thicker and more dangerous by the second, and quickly Gus realizes he’s in a very precarious situation. But he’s a different Gus from the Gus we had known for a season and a half. He’s the Gus of 20 years ago, who has many of the traits that the Gus we know does, but is a little more naïve and a little more trusting, even of his enemies.
