Ian Hart – Quirinus Quirrell

Meet Ian Hart, who gave us the ultimate chills as Professor Quirinus Quirrell in “Harry Potter.” There’s no denying that, as the Defence Against the Dark Arts teacher, he looked good in that turban that hid secrets like a pro in 2001’s “The Sorcerer’s Stone.” Since then, the English actor has been spreading his acting mojo like a potion gone wild.

Fast forward to 2018, he worked as Sailing Master Thomas Blanky in “The Terror,” the AMC-produced series. Two years later, Ian returned to his hometown and birthplace of Liverpool to play drug dealer Carl Sweeney in “The Responder,” the BBC One British police drama show, alongside Martin Freeman.
