Actor Emile Hirsch once intimidated several unsuspecting onlookers - after venturing off a film set with a temporary tattoo on his face.

The 22-year-old was required to shave his head and wear a tattoo of a zipper on his skull while filming the 2005 skateboarding drama Lords Of Dogtown - and he was stunned to see how people reacted to his bizarre appearance while out and about in Los Angeles.

He recalls, "There were days when I would leave the tattoo on and walk into bars. I thought it’s be fun to walk into these places with a tattoo on my face and a shaved head, and see people’s reactions.

"Everyone responds, and you get even more of a reaction than if you were, say, walking around with a celebrity!"
