Played by: Neal McDonough Most dastardly deed: Quarles kills Emmitt Arnett, the Dixie Mafia kingpin whose territory he wants for himself. Then he turns around and also puts a bullet in the head of Emmitt's secretary ¿ with whom he'd just slept. That's when we knew we were looking at stone cold evil. "When Quarles realizes he should probably kill her too, he's like, 'Aw, crap, really? OK. Bang," says McDonough. "I think playing it so simply made it more terrifying." Best line: Quarles, who favors $3,000 suits, slices a drug dealer's head open with a machete only to have the man's spurting blood ruin his Sean John tie. "What a ... !" he exclaims, invoking the male anatomy. McDonough says he improvised the line, and the crew "just fell out laughing." Ploy for pity: His heroin-addict father financed his habit by selling his young son to other men who, as McDonough puts it, "sodomized him right and left." Is it any wonder that Quarles' sexual proclivities include chaining up young men? You know you're in trouble when: The substance abuse begins. Quarles, a dealer in Oxycontin, begins popping his own pills when pressures on him mount. Next thing you know, he's naked and giving bong hits to hookers from a shotgun barrel. Then he's escaping a burning car with his back on fire. "I went full throttle on Quarles," says the actor. "I figured if he's going down, he's going down large."
