Chris Hemsworth worries about being boring

'Thor: The Dark World' star Chris Hemsworth says the biggest thing he worries about is to appear as a boring person.

The 30-year-old actor tries not to divulge much details about his life for he fears that others may take advantage of it, reported Contactmusic.

"'The biggest thing is you worry about being boring. I've worked with plenty of directors who are like, 'Yeah, but what's in there? Tell me about that time ...'And I'm like, 'Listen there is something in there, but I ain't gonna tell you and exploit it," Hemsworth said.

"'I hold that stuff pretty close'," he added.
