The Goonies is an absolute 80s classic, centring on a group of lovable misfits, who stumble upon some hidden pirate treasure but find themselves the target of a family of criminals headed up by Mama Fratelli.

However, what few fans of The Goonies know is that, in real life, the actor who played Mama Fartelli’s severely disfigured son Sloth, John Matuszak, had a truly tragic backstory.
