We first heard about the romantic thriller Napa in October, when Rose McGowan signed on to star.  The independent production has started shooting on location in Napa Valley, and a few more actors of note have joined the project.  Variety reports Sean Astin, Kevin Pollak, Johnathon Schaech, and Taryn Manning will round out the cast.  The story centers on "a woman (McGowan) who has recently returned from three Afghanistan military tours and is given the job of sheriff in her Napa hometown."Napa is the directorial debut of Michael Kerr.  Kerr co-wrote the script with Hans Ostrom.  Nellie Nugiel (Greek) is producing.
