It may be “all for one and one for all,” but it took director Richard Lester two films to contain the sweeping spectacle of Alexandre Dumas’s swashbuckling adventure. This sequel—shot simultaneously with The Three Musketeers, since they were originally conceived as a single film—dials down the comic high jinks that distinguished the first installment in favor of a more somber tone, as our heroes are drawn into a deadly revenge plot orchestrated by the seductive Milady de Winter (a deliciously wicked Faye Dunaway). Upping the psychological stakes and deepening our sense of the characters, The Four Musketeers brings this beloved tale of honor and friendship to a close with a rousing emotional flourish.
