Julianne Moore's uncanny take on Gov. Sarah Palin in the TV movie "Game Change," about the 2008 presidential campaign, earned her best actress honors. The political film from HBO was also honored in the best miniseries-movie category.
"I feel so validated because Sarah Palin gave me a big thumbs down," Moore said, beaming.
Kevin Costner was named best actor for History's wildly popular miniseries "Hatfields & McCoys," while Tom Berenger was named best supporting actor for the project and Jessica Lange won supporting actress honors for "American Horror Story."
Standup comic Louis C.K. won the Emmy for best comedy writing for "Louie" and for the special "Louis C.K. Live at the Beacon Theatre." Said the comedian after his second win: "Thank you to audiences around the country who still go to see live comedy."
Stonestreet won his second supporting actor award in a comedy in three years for his portrayal of a gay stay-at-home dad. The category was a testament to the strength of "Modern Family" in the comedy world: he beat three other actors from the show in Ed O'Neill, Ty Burrell and Jesse Tyler Ferguson.
Stonestreet noted the importance of going out Sunday and celebrating with the rest of the cast.
"We know this isn't going to last forever," he said, "and it will be the old show in a couple of years."
