As the King of Horror's new series 'The Institute' debuts, it's high time to watch his greatest TV triumphs.

For five decades, the fiction of Stephen King, 77, has been adapted for classic films: Carrie, The Shining, Misery, The Shawshank Redemption. But he's also made a mark on the small screen with dozens of TV shows and miniseries. On July 13, MGM+ premieres the new supernatural horror series The Institute, based on his 2019 novel of the same name, about a teen genius who wakes up in a facility filled with children of unusual abilities, overseen by the shadowy Ms. Sigsby (Mary-Louise Parker, 60). Later this year, Bill Skarsgård will return as Pennywise the Clown in the HBO prequel series It: Welcome to Derry, set in a fictional 1960s Maine town.
