"I auditioned for a role in this short film that was a horror short film about a clown that went around Green Bay... this is the first step of their viral marketing."

There. Mystery solved. 

"It’s getting a little bit scary because people are starting to believe it a little bit more, and we’re starting to see some of those unsettling pictures on Facebook," said the local actor. "Not of the clown, but of people armed and preparing to defend themselves, saying ‘I can’t go outside because I’m afraid of clowns or whatever. That’s just a little too far."

People were scared of the clown, and the clown was scared of the people.
