Rolling into Avengers: Infinity War, Chris Hemsworth wanted to make sure the Thor he and Taika Waititi crafted in their Ragnarok movie was present for the ensemble.
"I came into this and called Joe and Anthony and said, ‘Look, don’t write me the old Thor, we’ve got a new Thor now,’" Hemsworth told New.com.au. When the Russo Brothers, Joe and Anthony, told him the Thor they were directing would be something new, Hemsworth initially insisted it should not be. "I was like ‘no, no, no’ and I was really protective of what I’d created with Taika."
Hemsworth came around to some of the changes, though, when he realized the threat of Thanos was enough to alter the God of Thunder's perspective. "They then said, ‘No this is a whole different thing; Thor’s never faced something like this, never been a part of this large and ensemble,'" Hemsworth said. "I think for our characters it was difficult but for me a hugely exciting adventure."
Looking back at The Avengers and Avengers: Age of Ultron, Hemsworth felt like he had more to offer the ensemble films than he gave to the first two. "I felt stuck about what I was giving there and felt like I probably wasn’t bringing my portion to it as much as I could have"
