For example: The newspaper article photo of Chester Copperpot is really actor Keenan Wynn. And, more than 900,000 gallons of water were used in the movie. And, One-Eyed Willie’s name is actually William B. Pordobel, and his skull was made of real bone. And, Jeff Cohen was only 10 years old when he played Chunk.

You can really knock yourself out with Goonieness by also reading IMDb’s other extensive list, “The Goonies Goofs.” All in all, it’s a Goon-fest. (Photo: Warner Bros.)
