Chris Hemsworth had got "bored" of playing Thor before making 'Thor: Ragnarok'.
Chris Hemsworth as Thor
The 34-year-old actor has starred as the Norse God of Lightning in two 'Thor' movies as well as two 'Avengers' movie, and now he is reprising his role in the third instalment of the standalone franchise.
However, after portraying the superhero so many times he admits he hadn't been "giving everything" he could to the character and he asked Marvel Studios President Kevin Feige to give him something new to work with.
Speaking to Collider, Hemsworth said: "Even prior to the script I called Kevin and I said, 'I got to do something different. I'm so bored of myself. I don't think I'm giving everything.'
"I said, 'You've got to give me the opportunity to do something different,' and he was incredibly receptive and agreed and that set a bit of tone to the script and Taika [Waititi] came in and had the same ideas and thinking and it was the most fun, I think, I've had playing this character."
'Thor: Ragnarok' - directed by Taika Waititi - follows Thor in a race against time to prevent the all-powerful Hela (Cate Blanchettt) from destroying his home world and the Asgardian civilization.
At one point the hammer-wielding hero finds himself in a deadly contest that pits him against the Hulk (Mark Ruffalo), his fellow Avenger.
The movie marks the first time a female villain has been the main antagonist in a Marvel Cinematic Universe movie and the film also has the first LGBT character in the MCU, Valkyrie played by Tessa Thompson.
Hemsworth, 34, also said how he loved his scenes with Ruffalo, 49, because their two characters have "never really spoken on screen before".
He said: "I loved the stuff with Mark Ruffalo/Hulk and Thor because we never really spoken on screen before so we had all the room in the world to sort of invent that relationship. A number of times Mark looked at me after we had done an improvised scene and he said, 'Oh man are we wrecking this?'
"And I said, 'Good we need to break it,' and that was kind of every day and the same with Tessa. Tessa came in with this sort of Han Solo brash sort of confidence which was so different to Jane [Natalie Portman] in the previous movies and brought out a new quality in Thor.
"All of us have this same sort of attitude and hope we want from it. You know, it's a team effort."
Hemsworth and Ruffalo will reprise their respective roles in the upcoming 'Avengers: Infinity War'.
