The Russo Brothers were interviewed by Fandango as a promo for their upcoming "Avengers: Infinity War" and the most interesting tidbit gathered from this interview was the fact that, according to Joe, Thor and Thanos share the most screen time out of any of the characters.
Fandango: You mention some characters are invested with more screen time than others. Can you name which of those characters were invested more?
Joe Russo: Interestingly enough, I'll start out by saying Thanos, even though he's not a character that had a huge preexisting story in the Marvel universe. He was a threat but he was not developed in any way up to this point. Thanos has an incredible amount of screen time in this film, in a lot of ways I would say it's his movie. Our job when we make these films — and what we feel is important to us — is to surprise the audience. We wanted to tell a story that they weren't expecting, and the story is told from the point of view of a villain, which I think is also really unique and risky for a commercial film that will surprise the audience. I think this is a market where the audience really enjoys innovation and disruption, and we want to do something innovative in this space. So I think Thanos has an incredible amount of screen time, and I think you'll find that Thor has a really interesting arc in the film. He hasn't been at the forefront of other Avengers movies but he certainly has a very important role in this film. So I'll say, Thanos and Thor.
