'Thor' actor Chris Hemsworth has revealed that he doubted the Marvel epic would be successful before it was released.

Friends told Hemsworth that it was a bad idea to take the role of the Nordic God, as they believed the character couldn't be taken seriously.

While promoting his upcoming film, 'Rush (2013),' which documents the rivalry between Formula One drivers James Hunt and Niki Lauda, Hemsworth discussed his first thoughts on Thor.

Hemsworth told NJ.com, "There were plenty of people - more so than not - who told me from the start, 'Bad idea - this is going to be a disaster.' You know, big brooding brute in a blonde wig with a hammer?'"

The Australian actor originally dismissed these claims, but he suffered a crisis of confidence just before it finally hit multiplexes.

"Right before the film came out I suddenly thought, 'Damn, they might be right!'," noted Hemsworth. "But Ken struck just the right balance between entertainment and something a little more. Not too much more - you shouldn't take it too seriously - but the film had an integrity to it."

The 30-year-old continued his tribute to Kenneth Branagh, the director of 'Thor,' remarking, "There is a nobility to the character, and there's humour in the movie and I have to credit Ken."

Discussing the sequel, which sees 'Game of Thrones' director Alan Taylor replace Branagh in the director's chair, Hemsworth admitted, "The challenge was not to repeat what we've already done with the characters but to build on them, which is tough."

He then teased, "There's a great amount of comedy in the film, thankfully, but there's also a lot more about Thor and Loki and that relationship and what went wrong, and also all this unfinished business with Jane, Natalie Portman's character. So there's this kind of dance of conflicting interests, and a lot of action - the scope is certainly bigger than any Marvel film we've seen so far."

'Thor: The Dark World' will be released in the United Kingdom on October 30th.
