I have never seen ‘Helen of Troy” but the actress who portrayed her in “Troy” had a face which might have launched a few row boats but not a thousand ships.
Rosanna Podesta was Helen in the 1956 version of Helen Of Troy. Not a bad looker but I believe there are others whom could give her a run for the money.
A very young Bridget Bardot was also in the movie, a small part.
