Now that "Sex and the City" is over and done with, actress Sarah Jessica Parker is grabbing on to a few movie roles, one of which will be the dark comedy "Slammer." According to Variety, "Parker plays a pushy publicist who’s wrongly imprisoned on the charge she took fashion freebies meant for clients and turned them over to knockoff artists for mass production. Once in Sing Sing, she produces an inmate musical."Busy director Adam Shankman ("Bringing Down the House," "The Pacifier") will be helming the comedy, working from a screenplay put together by Sara Goodman, Tim Metcalfe ("Bones"), and John Slotnick. "Slammer" production is set to begin early next year.
