Jimmi Simpson

Jimmi Simpson is one of those actors who deserves way more name recognition than he gets, and I say that as someone who's watched him steal scenes for over two decades. He has this electric, slightly unsettling quality that makes him perfect for roles where you're never quite sure if the character is charming or dangerous — and honestly, he often plays both at once. His turn in Westworld as a young William was genuinely revelatory, anchoring the show's most compelling mystery with real emotional weight. Before that, his years on It's Always Sunny in Philadelphia proved he could do unhinged comedy just as convincingly as drama. A Theatre World Award winner with BAFTA and Emmy nominations to his name, Simpson is the definition of a working actor's working actor — versatile, committed, and criminally underrated.
