As far as minor characters go in the Fast and Furious cinematic universe, there aren't many as minor as FBI Agent Michael Stasiak. First introduced the series' fourth offering, the bungling agent initially appeared as a by-the-book foil/punching bag (literally) to Walker's "I'm a cop when I feel like it" Brian O'Conner. The character returned in Fast & Furious 6, and pretty much served the same function. Regarding the man who portrayed Stasiak, you've definitely seen his face before. Actually, you've probably seen it a dozen or so times in the last decade alone, because Shea Whigham is one of the most prolific character actors around. 

Among Whigham's big screen credits are indie gems like All the Real Girls, Tigerland, and Take Shelter. Whigham also appeared in higher profile fare like The Wolf of Wall Street, Silver Linings Playbook, and the wildly underrated Bad Times at the El Royale — not to mention blockbuster fare like Kong: Skull Island, First Man, and Star Trek: Beyond. On the small screen, the actor has claimed key roles in Boardwalk Empire, Marvel's Agent Carter, Fargo, Vice Principals, and the recent Amazon series Homecoming. If you haven't seen anything Shea Whigham is in, you might not be watching enough movies and TV.
