The brawl between the heroes has proven to be one of the most popular scenes in The Avengers, but Hemsworth said that staging the encounter was exhausting.
"It was tough, a lot of the time it was basically me with a harness on just getting ratcheted into a wall, then they were like, 'Throw yourself on the ground'. I was like, 'I'm not doing too well in this fight'," Hemsworth recalled, reports Flicks and Bits.
He continued: "It was rather painful, but then we have the nice big uppercut which I was thankful for. With that fight, a lot of the time it was me having to pretend… It was like being a kid in the backyard swinging a stick around.
"And then watching it come together and seeing that CGI creature in there, it was just very impressive. It would be funny to see some of the outtakes without the CGI, me sort of shadow-boxing the air."

"I honestly haven't seen the script. I know that Alan Taylor is directing, I've had a few conversations with him. If you've seen the Game of Thrones series, it has such a mythical element that Thor has, but also such an organic reality," the star said.
"A lot of real locations, as opposed to green screen, a lot of great sets. I know that is certainly something they want to do with the sequel, Thor 2. Make Asgard more liveable and more tangible."
Thor 2 is expected to hit cinemas in November 2013.
