The last three Avengers team-ups put Iron Man and Captain America in the foreground, but Infinity War will go in a new direction. Speaking to Fandango, co-director Joe Russo revealed that Thor is the lead hero, driving the main story alongside Thanos.
“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.”
Russo continued to drop hints on the decision making process.
“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.”
