Though not historically accurate you could say this film is based on Alexandre the Great's impressive figure. The point is that it has some important flaws the demerit the product.
First of all Richard Burton was not the actor to play Alexandre though not for his undoubted acting ability but because he was too old. In fact, he was almost the same age the Macedonian hero was when he died, and it shows clearly (even more when the picture takes his life when he was just an adolescent). Secondly, the film is too slow with lots of talk and little action, but Alexander was mainly a man of action. And finally, the not abundant action sequences lack spectacle and strength, even for the middle 50's. So it appears to me that director Robert Rossen either missed the correct focus to tell this story or got too tight to an erroneously focused script.
However the film might be entertaining for those who like epic films and/or are interested in the historical figure (like me) and has some good moments, good color photography, a fine and adequate musical score and a strong supporting cast.
Frederic March does a good job as Philipus II "the Barbarian", Alexander's father, who created the invincible Macedonian "falange" that was so very well used by his son at war. Danielle Darrieux plays Alexander's ambitious and confronting mother and there are fine performances too by Peter Cushing, Stanley Baker, Helmut Dantine and the always reliable Harry Andrews as Persian king Darius.
Just for a look every once in a while, but no too often.
