Chris Hemsworth worries his buff body could overshadow his acting career.

The hunky Thor star admits his physique has helped him kick off his acting career which includes high profile roles Marvel's The Avengers and Snow White and the Huntsman, but hopes it is his acting skills which keeps people interested.

"It's helped me get a job, sure. But you hope it's not the only thing that helped," he told GQ, speaking about his body.

Despite his good looks, Chris, 28, remains down to earth and admitted he finds some other actors' pre-shoot rituals strange: "I worked with a guy once who would chant, 'I'm beautiful and I have a secret, I'm beautiful and I have a secret.'"
