"It's Always Sunny in Philadelphia" star Glenn Howerton has become best known for playing the cynical, megalomaniacal bar co-owner Dennis Reynolds on the long-running FX comedy series, but his acting background is actually a bit more dramatic. Before he was screaming about being a five-star man or going on some of television's most unhinged tirades , Howerton attended the prestigious Juilliard School for the performing arts, and in 2014, we really got to see him show off his dramatic chops in a big project for the first time. After more than a decade in comedic roles on TV and playing bit parts in films like "Crank" and its sequel and "The Strangers" remake, Howerton took on the role of a personal trainer who got in over his head in the first season of FX's "Fargo."
