Who? Film director; actress.
Real? The tape reportedly existed, but it never circulated publicly.

During the first few days a total of forty-three officers would visit the crime scene, looking for weapons and other evidence. In searching the loft above the living room, Sergeant Mike McGann found a film can containing a roll of video-tape. Sergeant Ed Henderson took it to the Police Academy, which had screening facilities. The film showed Sharon and Roman Polanski making love. With a certain delicacy, the tape was not booked into evidence but was returned to the loft where it had been found.
This was 1969, two years before the first consumer videocasette recorder hit the market, which makes Polanski and Tate true pioneers of the homemade sex video. I’d love to know what kind of equipment and videotape format they used, but can’t really blame Bugliosi for omitting those details.
The Roman Polanski – Sharon Tate sex tape never circulated thanks to the courtesy and discretion of LAPD detectives. We’re probably all better off for that. The Manson story was creepy enough without a sex tape of the most famous victim circulating underground.
