Chris Hemsworth worried he would be blamed if 'Thor' flopped.
The 32-year-old actor was a relative unknown when he was cast as the hammer-wielding God in the 2011 Marvel movie but admitted he was afraid that if it didn't go well, the fans would turn on him.
Speaking to Vanity Fair magazine, he said: "When somethings costs $150 million and it doesn't work, it's your face, it's your fault. And the character has fans. Are they still a fan or did you just make them never want to read the comic again?"
Chris also opened up about getting the role over his younger brother Liam, 25, who originally got a call back when Chris didn't.
He said: "I had an audition with Ken [Branagh] that didn't go very well. I remember walking out thinking, 'Oh well, there goes that opportunity.' Then one day Joss [Whedon] and Drew [Goddard] were reading the trades, and on the front was the final four for 'Thor.'
"And they pointed to Liam and said, 'Hey, is that your brother?' And I said, 'Yeah.' And they said, 'Why the hell aren't you in the mix?' And I said, 'I didn't get a callback.' And they were like, 'This is crazy.' And I was like, 'If one of us gets it, that's cool.' And they were like, 'No way. That should be you.' And when casting opened back up, Joss called Ken and said, 'Give Chris another shot.' "
