Tommy Flanagan Tommy Flanagan

As Sons of Anarchy's Sargeant-at-Arms Filip "Chibs" Telford, Tommy Flanagan is used to finding himself on the wrong side of the law in front of the camera. But his latest role, Flanagan is going to have to answer to NYPD Fin (Ice-T) and Amaro (Danny Pino).

On Wednesday's episode of Law & Order: Special Victims Unit (10/9c, NBC), Flanagan plays Murphy, a sadistic Irish loan shark. "He ain't the most pleasant fellow," Flanagan says, "and apparently he likes to hurt people if they don't pay his money back."
