Played By: Giancarolo Esposito

Yoga. Yes, that's what Giancarlo Esposito cites as a key to his characterization of Gus Fring.

Audiences quickly tire of moustache-twirling, scenery-chewing villains. Breaking Bad's creator, Vince Gilligan, knew this, and approached Esposito with the idea that Fring should be created in opposition to our expectations of a villain, exuding detached serenity. The mild-mannered, tie-straightening fast food franchisee hardly feels like a cold-hearted villain at first blush, but that's exactly what makes Gustavo Fring memorable.

With the final episodes of Breaking Bad on the horizon, it remains to be seen if Gus or the corrupted Walter White (Bryan Cranston) will endure as Breaking Bad's all-time greatest villain. If White is going to outshine Fring's villainy by time the lights go down, the ex-chemistry teacher has plenty more havoc to wreak. It's often referenced that Breaking Bad was pitched as "Mr. Chips turns into Scarface." We're quite sure that Gus would have poisoned Tony Montana before he was asked to say hello to his little friend.
