Brescia's third film is yet another peplum film that touches somewhat familiar territory but manages to pull off very well the same spirit of fun and light adventure present in some of the greater examples of the genre. His own take on the myth of Hercules seems rather derivative, kind of what we have seen in Hercules at the Conquest of Atlantis (1961) but done in a much less polished and notably cheaper way, leaving behind almost all mythic lore and opting for a rather self contained new sci-fi/fantasy background for the lost civilization. Because of this, Heracles feels less mighty than Hercules but his struggles and journey are almost as effective.
Incredibly well-paced, action driven, colorful and magnificently psychotronic. This is an interesting piece of peplum cinema that serves as a curious addition even if it's not new territory at all. You can tell this is early Brescia as there are some seeds but he hasn't fully gotten to the highpoint of pulpy cinematic sublimity he reached during his space movie cycle.
