LOS ANGELES, USA - Movie star Sly Stallone's first ever starring role in a softcore sexy party   shot in the 1970s before his acclaim to fame in the 1976 smash hit Rocky, has sold for $412,000 on ebay.

The film entitled 'The Party at Kitty' has been kept mostly under wraps for decades, however the one time erotic outing for the action star has become something of a peculiar fascination in today's celebrity culture.

Once offered $100,000 to buy the full ownership of the film, Stallone passed, as it wasn't a big deal for him. Now today it would seem that people will be taking notice as the ebay auction included the worldwide rights, and original 35mm negatives.

Sylvester Stallone chose to do the 2 day shoot after getting desperately low on cash. The actors survival mode was in full swing when he took the role of an alpha male who invites a crowd to his apartment that he shares with his girl Kitty for a sex party.

Stallone before 76 was practically living on the streets, and had been offered the quick $200 that saved the day.

"I'd been bounced out of my apartment and had spent four nights in a row at the Port Authority bus terminal, trying to avoid the cops, trying to get some sleep and keeping my pens and books in a 25-cent locker," he said. "I mean, I was desperate." - Gaurdian.co.uk
