Abs of The Day: James Franco Goes Shirtless on The Set of His Gay Adult Film Biopic

Actor James Franco stripped down yesterday on the set of his new gay adult film biopic King Cobra, and things got steamy.

Franco's production company is producing the film, which is based on the 2007 murder of gay adult film maven Bryan Kocis. He appeared on Instagram next to actor Keegan Allen, clad only in a pair of skimpy underwear.

Disney Star Garrett Clayton (below left) will also appear in the movie, playing adult film star Brent Corrigan (below right).

The crime at the center of the film happened in 2007 when Harlow Raymond Cuadra (below left), and Joseph Manuel Kerekes (below right) murdered Kocis, owner of Cobra Video.

They tried to lure Corrigan away from Kocis, police say.
