Whether she's starring in horror movies like Suspiria, indies like Only Lovers Left Alive, or superhero blockbusters like Doctor Strange, Tilda Swinton brings her A-game to every movie she's in. But despite her impressive thespian powers, Swinton has only once been nominated for an Oscar. Fortunately, she walked away with that golden statue for her performance in Michael Clayton, a 2007 movie that finds Swinton as a vicious but anxious attorney named Karen Crowder.

Crowder is a lawyer for a major company that has knowingly produced a carcinogenic weedkiller. She'll do anything to cover for the company, even if that means murder, but while she's a cold-blooded killer, Crowder is on the verge of a nervous breakdown. Swinton makes this villainous attorney both scary and sympathetic, whether she's ordering a hit or suffering a panic attack in a bathroom stall. She creates a fully rounded and completely realistic villain in just 18 minutes, and while she doesn't have much screen time, that didn't stop her from winning that Best Supporting Actress Oscar.

Hilariously, Swinton was underwhelmed when she showed up to the 80th Academy Awards. See, she'd never actually watched the Oscars before, and she told Rolling Stone, "I remember being a little bit disappointed that it wasn't more magnificent, [that] it wasn't in a bigger room." She then realized she was disappointed was because she'd expected the ceremony to be like the one in the Kevin Costner-Whitney Houston movie The Bodyguard — larger than life and full of assassins. Fortunately, the only killer that night was Swinton, when she murdered her competition.
