Josh Brolin is probably one of those rare actors who become famous for a role before they even played it. His casting as the ultimate Marvel villain Thanos generated tremendous buzz and curiosity among fans. And after almost five years of teasing his role in the Marvel Cinematic Universe, the character will appear in a full-fledged role in the upcoming two-part "Avengers: Infinity War"

During a recent interview with Moviefone, Brolin revealed he's heard the full script and story of "Avengers 3" and it really blew him away.

"Yeah, I sat at a table and I listened to the story from beginning to end, which was ... you know, sometimes you go around and you go, 'Oh, it's a great movie. Or this is a great experience,'" Brolin explained. "And you kind of know that it's not. This is the opposite."

The actor then talked about how Thanos is his most-talked-about role to date. "First of all, from a publicity point of view, or an interest, I've gotten more publicity playing Thanos, even though I haven't done it yet, than all other movies combined," he said.

He added: "Then the other side of it is really how much it means to people. These Avengers stories all come down to this conclusion, and that's our involvement. Basically, my character against everybody. And it's really fun what they've chosen to do with the story. I think it's brilliant, personally. I was blown away, and had goose pimples pretty much 50 percent of the time that I was listening to what was going on, and pretty amazed that I'm going to be involved in it. So it's a big thing that's coming up."

Directed by Joe and Anthony Russo, the tentatively titled "Avengers: Infinity War" Parts 1 and 2 will start filming in November, with Part 1 releasing on May 4, 2018 and Part 2 on May 3, 2019.
