Watch a Nightmare on 19th Street Actor Scare People Senseless With a Chainsaw

We strapped a GoPro to a Nightmare on 19th Street actor wielding a chainsaw and gave him one simple task: scare as many people as possible.

The actor's costume resembles Leatherface from the "Texas Chainsaw Massacre" movies. And he's every bit as imposing as Gunnar Hansen when he's swinging around his chainsaw. You don't see that. However, you do see a bunch of people screaming in terror and running away.
