Crowning Moment of Awesome: The Musketeers fighting forty soldiers is easily the high point of the movie. The elements are terrific (Porthos using anything at hand, Athos slamming through ten guys without breaking stride) and the fantastic musical score just makes it all the better.
Genius Bonus: Or rather Reader Bonus. Luke Evans (Aramis) bears a resemblance to Orlando Bloom (the Duke of Buckingham). In the book, when D'Artagnan first sees the Duke he notes his resemblance to Aramis.
Germans Love David Hasselhoff: The movie was a flop in the US but has been quite successful overseas (even managing to be of the year's biggest films in Germany and Japan).
