Teresa Ann Savoy was born in London in 1955 but ran away from home to a hippie commune in Sicily when she was 16. At the age of 18 she posed for the Italian version of Playboy called "Playmen" and then began an acting career in 1973 with her first role as a sexually promiscuous and developmentally disabled girl in Alberto Lattuada's Le farò da padre aka I'll Take Her Like a Father.
Then in 1974 she donned a prosthetic penis to play the hermaphrodite Baroness Mary Vetsera in Miklós Jancsó's Public Vices, Public Virtues.
But she is primarily known for her roles as a sex toy for the S.S. in the nazisploitation Salon Kitty and as Caligula's beloved sister Drusilla in the major motion picture/porn Caligula, which Roger Ebert described as "sickening, utterly worthless, shameful trash" before walking out in the middle of the screening. I'm not sure what he was talking about, though. The scene where Caligula has sex with Drusilla's corpse didn't even make it into the movie.
