The short life and quick death of Alexander the Great is recounted in this literate historical epic. Decked out in a blonde wig, Richard Burton stars as the Grecian warrior who conquered the known world while only in his twenties, then wept because there were no more worlds left to conquer. While the film's 141 minutes are occasionally bogged down by near-existential dialogue sequences (What doth it profit a man etc. etc.), the battle sequences are among the best and most accurate ever filmed. Fredric March and Danielle Darieux costar as Alexander's parents Philip of Macedonia and Olympius, Claire Bloom does what she can with the nothing role of Alexander's wife Barsine, and Michael Hordern and Harry Andrews are cast as Demosthenes and Darrius, respectively. Lensed in Spain and Italy, Alexander the Great conquered no new worlds at the box-office, perhaps because Richard Burton, brilliant though he was, hadn't yet attained "saleability".
