Sylva NOT Sylvia Koscina
Sylva Koscina was born in Yugoslavia, which may account
for the spelling of her name. She was credited variously as
Sylva, Sylvia, Silvia, and Silva. You can find lots of pictures
online by searching her wrongly as "Sylvia." She is best
remembered for her appearances in Hercules (1958),
Hercules Unchained (1959), The Secret War of Harry
Frigg (1968), and Marquis de Sade: Justine (1969).
Me, I like her best in Deadlier Than the Male (1967).
Anyway, her name is "Sylva" and not "Sylvia."
