As 2011 winds down, Moviefone has offered you every form of best-of lists, including the sublime (the 50 best movies of 2011) and the surreal (best top movies?). Next up on the countdown? The best performances of the year! From the traditional (Meryl as Margaret Thatcher) to the untraditional (Uggie the dog), 2011 was chockablock with great work from actors and actresses. Ahead, the 11 best of the year.
