Deftly balances the inherent comedy of royalty and the emotionally devastating effects of mental illness. I hope whoever was in charge of the wig department got an award for this. The epilogue glosses over the fact that poor George's madness eventually became permanent and mischaracterizes the king's return as final instead of the temporary triumph it really was.
Hawthorne is just about perfect, Holm and Mirren are superb, in spots it's genuinely very funny, and there are some great tracking shots. But it has too many characters for its own good, lacks focus, can't really settle on a tone, and it makes for a very superficial movie that never really lets us into what's going on. A respectable but cautious film, saved from tedium and irrelevance by a great lead performance.
