Josh Brolin

Josh Brolin has played a number of comic book characters to date. At present, he is portraying Thanos in the Marvel Cinematic Universe. He made his debut as the Mad Titan in Guardians of the Galaxy, reprised the role in Avengers: Age of Ultron, and will do so again in the upcoming Avengers: Infinity War movies. His portrayal of Thanos isn't just voice acting, as it also includes motion-capture. And, as he plays the character in live-action movies, it is worth mentioning.

Back in 2010, he portrayed the titular superhero in the DC Comics adaptation, Jonah Hex.

In Sin City: A Dame to Kill For, Brolin appeared as Dwight McCarthy, a character played by Clive Owen in the first movie.

He also portrayed the younger version of Tommy Lee Jones' Agent K in Men in Black 3.
