"Naruto Movie Four"
Coming August 4th, 2007
What do we know? It has yet to be stated at what point in continuity this movie will take place, but we do know it takes places in the post-timeskip Shippuuden time frame. The movie will come to theaters close to Shippuuden episode 25, putting it around the start of the second Naruto arc. Like the previous movies, movie 4 will probably exist in its own continuity, outside of the main storyline. Due to the use of filler in the anime, the movie will probably fit into its continuity.
What is the story? At this point we don't have much to go on. Apparently Naruto battles a group of ten individuals who "kill" him. Naruto's friends then have to deal with his passing.
What do I think? Taking place in the post-timeskip time frame and involving a darker subject matter may set this movie apart from its more lighthearted predecessors.
