John Waters is back in the director's chair and his casting remains as eclectic as his oeuvre. Parker Posey and Johnny Knoxville have signed up to star in the filmmaker's newest Christmas fare Fruitcake. The Hollywood Reporter (said today that "The plot is officially under wraps but is said to center on the title character, a boy named after his favorite dessert. He runs away from home during the holidays after he and his parents are caught shoplifting meat, then meets up with a runaway girl raised by two gay men and searching for her birth mother." Being that Fruitcake is a John Waters film, that sounds about right.
