Richard Grieco recently began production on his upcoming horror flick, "Clinton Road," when his crew decided to have a little fun at his expense.
Grieco's film is about New Jersey's Clinton Road, a spooky, urban legend-filled 10-mile stretch known as "America's most haunted road."
So, naturally, the film's director, Steve Stanulis, drove Grieco out to the road in the middle of the night under the guise of talking about the film.
We won't spoil what happens next, but you gotta watch Grieco lose his mind.
We're told Stanulis and the crew eventually let Grieco know it was all a prank ... after letting him freak out for a while.
