"Godzilla Final Wars", the latest in the series, which will surely be the best of the stories, started its production with all the ingredients of the past 27 films over the past 50 years. More than 10 monsters which colored the series as well as the newly improved King of the Monsters "Godzilla" will appear in the film and show us the movements and terrors that we have never seen before.
The film has the best cast ever in the series. Masahiro Matsuoka of TOKIO is the leading star and Rei Kikukawa plays the heroine. One of the top professional fighters, Don Frye, Kazuki Kitamura, Kane Kosugi, and Miki Mizuno are co-stars. Akira Takarada who starred in the first Godzilla film as well as the series veterans such as Kumi Mizuno and Kenji Sahara will also appear in this film.
The film is directed by Ryuhei Kitamura who is the hottest Japanese filmmaker in Hollywood. The film indeed has the best cast and crew in the series history.
