Thor: Ragnarok provided a fairly radical change in tone for the Asgardian hero, and that tonal shift was embraced by the Avengers: Infinity War screenwriters.
Avengers: Infinity War screenwriters Christopher Markus and Stephen McFeely were asked in a recent interview about how much of an impact Thor actor Chris Hemsworth had on the character in the Avengers films. "Hemsworth came to set and went, 'You guys really need to understand that we are doing something different with Ragnarok,'" McFeely told The Hollywood Reporter. "And we knew they were changing it some, but it was so early in the process, so we flew [Ragnarok screenwriter] Eric Pearson and [director] Taika Waititi in and we had long conversations with them."
"There are at least a couple of jokes in there Taika himself said in passing that we thought were gold," McFeely continued. "They showed us a few scenes, so we knew that Thor was being re-toned. And we needed to embrace that."
"But it was also the realization that even in the 'funny' one [Ragnarok], his father and his sister die, and that he's almost becoming comically unlucky at this point, and to follow that to its natural conclusions," Markus added.
In theaters now, Avengers: Infinity War is directed by Joe and Anthony Russo and stars Robert Downey Jr., Chris Evans, Chris Hemsworth, Mark Ruffalo, Jeremy Renner, Scarlett Johansson, Paul Bettany, Anthony Mackie, Paul Rudd, Elizabeth Olsen, Tom Holland, Benedict Cumberbatch, Chadwick Boseman, Chris Pratt, Zoe Saldana, Dave Bautista, Bradley Cooper, Vin Diesel, Tom Hiddleston and Josh Brolin, among others.
