And here we thought the celebrity sex tape phenomena was a modern development in the entertainment industry.

The footage appears to have been shot in the 1950s. When it came to light in the mid-’60s, then-FBI Director J. Edgar Hoover had his agents spend two weeks futilely trying to prove that Monroe’s sex partner was either John F. Kennedy or Robert F. Kennedy, according to declassified agency documents and interviews, Morgan said. The silent black-and-white flick shows Monroe on her knees in front of a man whose face is just out of the shot. He never moves into the shot, indicating that he knew the camera was there, but Monroe never looks at the lens, said Morgan, who saw the footage.”

Apparently somebody bought the film for $1.5 million, proving once again that people will buy anything.
