Richard L. Coe of "The Washington Post" wrote that the film "is, for a movie, so remarkably faithful to historical fact that it is more the pity that, as a movie, it is so boring ... Such is the power of detailed pictures that repetition of battle scenes, leave-takings, orations and intrigue simply becomes dizzyingly meaningless." "Harrison's Reports" wrote, "Beautifully photographed in CinemaScope and Technicolor, it is without a doubt one of the most opulently mounted pictures ever produced, a magnificent eye-filling epic with a scope and splendor that is alone worth the price of admission to see." John McCarten of "The New Yorker" wrote that "while the picture has plenty of interesting pageantry, it doesn't offer quite enough drama to hold one's attention for its full length—a matter of two and a half hours. Far too much of that time is spent in detailing the Macedonian's unhappy youth." "The Monthly Film Bulletin" wrote, "Conviction is considerably dissipated here by Rossen's refusal, in spite of obviously serious intentions, to present character in terms much more convincing than those of comic strip history ... The battle sequences are well composed, but the generally pedestrian style and approach of the production ultimately reduce "Alexander the Great" to a well-intentioned historical jamboree, protracted and intermittently quite enjoyable."
