The awards show gives actors a chance to honor their peers in a ceremony that often (historically) sheds light on who will go home with an Oscar next month.
And features an A-list red carpet, of course ...
The best in TV are also honored, with the Boardwalk Empire and Modern Family casts receiving the top accolades. Who else took home the trophies last night?
