Who remembers Roman Polanski and Sharon Tate? Polanski allegedly forced Tate to have threesomes and film adult tapes so he could share with friends. Here she is with her hairstylist before they were both brutally murdered.

So Roman Polanski and his wife Sharon Tate were kind of swingers. It was the 60s, though, and free love was one of the mantras. Here's Tate with Jay Sebring, who was a hairstylist to the stars - and also one of the murder victims at the hands of The Manson Family. Sebring was introduced to Tate by a journalist in October 1964 and they started going out. They ended their relationship in 1966, when Tate went to work on the movie The Fearless Vampire Killers - which was directed by Roman Polanski.
This shot of Tate and Sebring was taken by photographer Voytek Frykowski - on August 1969, the day before they were murdered by The Manson Family.
