The actor discussed the involvement of Game of Thrones director Alan Taylor, who will replace Kenneth Branagh at the helm of the thunder god's second big-screen outing.
"What I love about that series is the mythical element to it, but that world that they lived in was entirely tangible and organic," Hemsworth told The York Press regarding the adaptation of George RR Martin's novels.
"It was all real locations, not green screen... I think Thor and Asgard could use that. That would be a huge plus, to not have worlds that are too clinical and ethereal, and have places that look like they have existed for thousands of years. I think this would be more locations and less green screen."
The actor admitted that he has yet to see the completed script.
"I haven't got a script yet for Thor 2," he said. "I do get input into the script to a degree."

Various cast members from the first film - including Idris Elba and Jaimie Alexander - have hinted that they may return for the sequel. Tom Hiddleston is also expected to reprise his role as Thor's stepbrother Loki.
Hemsworth and Hiddleston will both appear in The Avengers, which opens in UK cinemas on April 26, and May 4 in the US.
