Not much is known about Thanos heading into Avengers: Infinity War, but Josh Brolin -- who will play the Mad Titan with the help of motion-capture technology -- revealed that the film will explore the villain's younger days on his home planet of Titan.
In an interview with Entertainment Weekly, Brolin was asked where does Thanos' anger and pain come from, and why is it that he's so damaged.
"He’s different from his family," Brolin replied. "They’re all Titans and they all look similar, but he was born deformed. You see how he grew up, you see he was like the Quasimodo of this time, or if you’ve ever read Perfume [Patrick Süskind ‘s 1985 novel about a serial killer who craves beautiful scenes but is disgusted by the smell of humanity], it’s a great parallel to Thanos. He stuck out. He was an anomaly. He was a freak. And that lent to this apparent insanity."
While Infinity War will tweak Thanos' motivations to be on the nobler side, some of his comic book origins will remain the same. In the Marvel Universe, Thanos is born as a mutant child on Titan, where he became an outcast among his people because of his physical appearance. The same aspects of the character will be adapted from the comic page to the big screen, making for a smooth transition and easing the minds of any fans who may have been worried that Thanos would be drastically different from his comic counterpart.
