An illicit copy of an apparently “steamy,” still-FBI-classified film reel — 15 minutes of 16mm film footage in which Marilyn Monroe performs oral sex on an unidentified man — was just sold to a New York businessman for $1.5 million.

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.

You know what would be even cooler than a Marilyn Monroe port-mortem sex tape? A Paris Hilton post-mortem sex tape, released the day after tomorrow.
