We have the first official clip from Necessary Evil: Super-Villains of DC Comics, an all-new documentary produced by Warner Bros. Home Entertainment and DC Entertainment, on Blu-ray/Blu-ray Combo Pack this Friday, October 25, 2013. Watch as Guillermo del Toro discusses the similarities between the good guy and the bad guy, and why it's important that they have a commonality amongst their goals.

Necessary Evil: Super-Villains of DC Comics explores the thin line between right and wrong, the nature of evil and how super-villains can reflect society's dark side as well as our own personal fears. It also offers keen insight as to the reasons why comic book fans are so fascinated by the very characters they hope to see defeated. The film focuses on DC Comics' most terrifying villains, including The Joker, Lex Luthor, Bane, Black Adam, Black Manta, Catwoman, Darkseid, Deathstroke, Doomsday, General Zod, Sinestro, the Suicide Squad, and more.
