Marvel fans have been waiting a long time to see the super villain Thanos in a full-fledged role. The Mad Titan has been teased several times in earlier films, but is expected to take on The Avengers in the two-part Infinity War. Will Thanos succeed where Loki and Ultron failed? Well, of course not, but he's sure to put up a bigger fight.

Actor Josh Brolin, who plays Thanos in the MCU, recently spoke about taking on a role which is the "opposite of anything he's ever done." The actor told ComingSoon.net (via SuperheroHype), "I was in England and I was doing Everest during [while] making that decision [to play Thanos]... And strangely enough - and I'm always surprised by what I decide to do right away and what you say no to especially in hindsight - Thanos was almost immediate. I looked through a book that they had sent me and was like 'God this is amazing.'"

In another interview with MTV at the Toronto International Film Festival, Brolin explained further how the decision to play Thanos was "very easy" for him despite turning down several similar offers previously. "I'd turned down a lot of these things or bigger movies and immediately they sent me a huge book of all [executive producer Louis D'Esposito's] stuff because I wasn't too familiar. I was in England doing Everest, I was halfway through the book and I was like, 'I'm so in.'" Well, now we just have to see Brolin's take on the popular comic book villain when he appears on the big screen again in Avengers 3: Infinity War or (hopefully) sooner, in Guardians Of The Galaxy Vol 2.

Marvel's Avengers: Infinity War - Part 1 and Part 2 will reteam Captain America: The Winter Soldier and Civil War screenwriters Christopher Markus and Stephen McFeely with co-directors Joe and Anthony Russo. Filming will reportedly begin in October 2016. Avengers: Infinity War - Part 1 opens on 4 May 2018, and Part 2 will release on 3 May 2019.
