Shakespeare does not always adapt well to cinema. This, however, is a stunning and quite sublime adaptation. The cast is quite outstanding (Ian McKellen proving now that Gandalf in Lord of the Rings is not his first great performance). The TRUE genius, though, is from Richard Loncraine, Director. Loncraine has long been associated with the very best of British and American drama (Brimstone and Treacle, and Band of Brothers where he directed undoubtedly the finest part, episode 2, being two better known examples). The dark and powerful nature of this play is brought out in the most profound manner by Loncraine who confirms his place as one Britain's - and therefore the World's - finest directors.
Buy this film. On DVD if you can, or on VHS if you can't. You will not regret it.
