Bordellet
Bordellet is a 1972 Danish theatrical sex comedy film made by pornographic pioneer Ole Ege and was Denmarks first fulllength hardcore pornographic feature film.
At the films release party, Danish millionaire Simon Spies showed up, took off his clothes and started having sex with members of the films female cast in front of the press. The resulting photos naturally made front page news and are still reprinted frequently.citation needed
