He’s been promised to be Marvel’s baddest villain, but for all the hype, we don’t really know much about him.

We sat down with Josh Brolin (a.k.a. Thanos) to find out what we can expect when we see Avengers: Infinity War. 

How evil is he? “That’s up to you!” Brolin exclaims. “He’s a much smarter character than we imagined him to be. I like the mystery.”

“He blindsides all of us,” Zoe Saldana (a.k.a. Gamora, a Guardian) says. “He’s not just threatening the destruction of a planet—it’s the universe.”

He’s a majorly complex character, with both good and bad in him—and that’s what makes him such a good villain!
