Godzilla: Final Wars is the fiftieth anniversary film and the twenty-eighth film in the Godzilla film series. It was directed by Ryuhei Kitamura and produced by Shogo Tomiyama. As a 50th anniversary celebratory film, a large group of actors from previous Godzilla films, both classic and new, made appearances as main characters or cameo appearances. This goes for the kaiju (monsters) as well, as most of the monsters in the film had been missing from the screen for more than thirty years. This is the only Godzilla film, from the Japanese series, to receive a PG-13 rating by the MPAA. The only other Godzilla film to receive this rating is the American remake of Godzilla. Despite the title, this is not the final Godzilla film; Toho has decided to temporarily "retire" the character for a period of time (possibly around 2013 or 2014) in order to renew interest in the future for Godzilla's 59th or 60th anniversary.
