A press release describes the hour-long movie, Extra Action (And Extra Hardcore), as the result of what happens when photographer/filmmaker Richard Kern tells his "unpretentious, unadorned, and definitely undressed 'real women' to "roll around and do something interesting for a few minutes." The DVD comes out March 18 via MVD, and in addition to Thurston's original score for Extra Action, it features previously unreleased Kern flicks as extras.  Source
