Barry Jones and Susan Hayward are Claudius and Messalina in DEMETRIUS & THE GLADIATORS
I didn't much care for Susan Hayward's acting style when I initially saw this film. But I've watched many of her films since, PEPLUM or not, and I've changed my mind for this role. She's pretty good. Yes, her tics and mannerisms are present, which are needlessly distracting, but I now appreciate her take on Messalina. She could have been more cruel but that's how Messalina was written for this film. Barry Jones' British accent in a film with a mostly American cast is also quite distracting.
Good film. Much more PEPLUM-like than its predecessor, THE ROBE. In fact, this is one of the best PEPLUM films made in Hollywood.
