The song "The Greatest Love of All" was written for this film by Michael Masser (music) and Linda Creed, (lyrics) and sung by George Benson; it was later covered and made a Billboard Hot 100 #1 single by Whitney Houston.

Vincent Canby of The New York Times called the film "a charming curio of a sort Hollywood doesn't seem to make much anymore."^[6] Kevin Thomas of the Los Angeles Times called the film "potent pop biography, lively and entertaining, in which the irrepressible world's heavyweight boxing champion projects exactly the image he wants us to have."^[7] Gene Siskel of the Chicago Tribune gave the film 2.5 stars out of 4 and wrote, "As a diverting entertainment, 'The Greatest' is more than satisfactory."^[8] Arthur D. Murphy of Variety wrote that Ali brought the film "an authority and a presence that lift John Marshall's production above some of the limitations inherent in any film bio."^[9] David Badder of The Monthly Film Bulletin stated, "The Greatest delivers exactly what one would expect: a hagiographical account of Ali's best-known exploits, giving full rein to the inimitable, volatile personality but in the process applying liberal coats of whitewash."^[10]
