Not a great movie, this was (as has been pointed out) a pilot for an unsold television series (produced by Joseph E. Levine, who distributed the original Steve Reeves HERCULES) based on the adventures of Hercules. I remembering looking forward to this after seeing a magazine article featuring Carlo Rambaldi's sea monster. In truth, the monster is the only thing worth watching in the show. It's well crafted but badly used. In a few shots it looks very convincing, in others like a big mechanical puppet pointlessly waving its claws around. Still worth checking out for pre-CGI monster fans and Gordon Scott makes a solid Hercules as usual.
