While not exactly a household name, Jason Isaacs has very quietly put together an impressive resume of villains over his 30 years in Hollywood. Anyone who was in high school in the late ’90s will remember him from Mel Gibson’s The Patriot — I can’t possibly be the only person who had a lazy substitute history teacher, right? — but he’s also worked regularly in film and television, from frequent collaborations with Resident Evil director Paul W.S. Anderson to his most memorable role in the Harry Potter franchise. Often evil, always great.
