She was born Scilla Gabellini, one of five siblings, in Rimini on the Adriatic coast. Scilla initially studied law at Oxford University, graduating with a doctorate. Her interest in pursuing a legal career waned quickly, however, since her next move was a return to Italy for acting classes at Rome's Accademia Nazionale d'Arte Drammatica. At the age of seventeen, the voluptuous, blue-eyed Scilla became a body double for Sophia Loren (to whom she bore more than a passing resemblance), notably in the classic Boy on a Dolphin (1957). Two years later, she underwent cosmetic surgery to look less like Sophia in order to forge her own screen image.
