Michael B. Jordan
The Wire wasn’t Jordan’s first HBO gig: The Creed star played one of Tony’s (James Gandolfini) childhood bullies in a Season 1 episode of The Sopranos.
Back when Hamilton was just a glimmer in Miranda’s eye — and long before the return of Mary Poppins — this actor and composer played a hotel bellman in the show’s sixth season.

Speaking of Shondaland stars, this Grey’s fan favorite guest-starred in Season 5 as a woman who argues with Janice at an anger management class.
