Circumstance: Young actor

In 2006, the news broke: Jackie Chan from Rush Hour did a porno! The actor shrugged it off, admitting that yes, 31 years prior, he had appeared in the Hong Kong-made adult comedy, All in the Family. Hell, Sammo Hung, who entertained audiences from 1998-2000 on Martial Law and has a much pornier name, was in it too.
