Poltergeist III (otherwise known as Poltergeist 3 or Poltergeist 3: We're Back) is a 1988 American horror film. It is the third entry in the Poltergeist film series. Writers Michael Grais and Mark Victor, who wrote the screenplay for the first two films, did not return for this second sequel; it was co-written, executive produced and directed by Gary Sherman, and was released on June 10, 1988, by Metro-Goldwyn-Mayer Pictures. The film was panned by critics, and was a box office disappointment.
Heather O'Rourke and Zelda Rubinstein were the only original cast members to return. O'Rourke died four months before the film was released and before post-production could be completed. It was dedicated to her memory.
