The 32-year-old Australian actor said contrary to his belief that no one will recognise him in prison, it became really hard for him to hide his Thor looks, reported People magazine.
"I was researching a film and we had to basically go in and research what the inside of a prison looked like and speak with prisoners who wanted to talk to us.
"I assumed no one will recognise me and the moment I started walking through the cells...I just started getting heckled, 'Yo, Thor's here man. Yo Thor, YO THOR!'," Hemsworth said.
