John Gallagher Jr.
Notable Role: Jim Harper in The Newsroom
John Gallagher Jr. gives a stellar performance as the loyal producer, Jim Harper, in HBO's behind-the-scenes news drama, The Newsroom, but the 29-year-old has been building acclaim for years. Which is to say, if you're a fan of Broadway, you already know he's a superstar. He's a Tony Award winner for originating the role of Moritz in Spring Awakening. We're pretty confident in his ability to earn some more attention, and awards. His movie, Short Term 12, where he stars as a foster care supervisor opposite Brie Larson, was the Grand Jury winner at SXSW.
