WHAT LIES BENEATH opens. Directed by Robert Zemeckis. Written by Clark Gregg, from a story by Gregg and Sarah Kernochan. Harrison Ford and Michelle Pfeiffer stub their toes in contrived, sub-par Hitchcockian murder mystery precariously reinforced by a litany of hoary supernatural horror tropes more befitting a Corman or Hammer quickie. With Diana Scarwid.
