The King's Speech is about a king (Firth) with a stuttering problem who must give a stirring, patriotic speech to his citizens as Britain enters WWII. His wife (Bonham Carter) enlists the help of a peculiar linguistics coach (Rush) as a last resort. As far as plot goes, that's about all there is to it. Although it's a simple story, it is exquisitely told. With perfectly composed shots, precisely metered pacing, and superb acting, the film rises above its straightforward writing. Colin Firth is magnificent in his role, bringing sympathy without pity to a nuanced, intricate character. He manages to be both intelligent and tender, manages to instill both strength and levity. Bonham Carter and Rush do fantastic jobs in supporting roles to make the whole thing an acting powerhouse. Unfortunately, the rest of the movie doesn't stand out quite like the acting does. It's perfectly competent technically, but all you'll remember when you think back on the movie is how good the acting is. And it is really good.
