From the myriad of stories and characters that would be great as a TV series, the first thing that pops-up in my mind is a series based on the Argonauts. Hercules would appear from time to time with each member of the crew getting storylines. It would very cool and fascinating. HERCULES (1958) was the first motion picture to focus on the fabled crew of the Argo. THE GIANTS OF THESSALY (1960) and JASON AND THE ARGONAUTS (1963) were other movies which were based on the Argonauts. Those movies showed how we barely knew all the members of the crew. A TV series would give time to explore and expand all the adventures, old and new, the men experienced.
The actors are: Fulvio Carrara as Castor, Willy Colombini as Pollux, Fabrizio Mioni as Jason, Aldo Pini as Tifi, Steve Reeves as Hercules, Gabriele Antonini as Ulysses, Andrea Fantasia as Laertes and Gino Mattera as Orpheus. From HERCULES (1958).
