Agatha Harkness on 'WandaVision' and more of the greatest witches in pop culture

"The Queen's Gambit" star Anya Taylor-Joy made her feature film debut in 2015's "The Witch," a truly terrifying film about an isolated Puritan family that's targeted by dark forces in 17th century New England. What makes the movie -- which has a 91% fresh rating with critics on Rotten Tomatoes -- so unique is that the title doesn't necessarily refer to the character you might think. Saying anything more would take away from the thrill of watching this underrated treat for the first time!
