The fourth movie in the serie, titled Naruto Shippuuden: The Lost Tower, will feature a special in which Naruto and his friends will struggle with a bottle that contains a genius that can grant wishes. A little out there, but we know that omake is always fun.
The movie will premiere on Japan on July 31st, and it's a about a mission that was assigned to our protagonist, in which he has to capture Mukade, a missing-nin that hides in the mythical ruins of Ouran. After cornering him, Mukade reveals that he is after a leyline that allows time travel. He gathers it and uses it on Naruto, who is sent 20 years in the past and then he meets his father, Minato Namikaze!
Sounds predictable, but hey, at least we get some kick ass animation!
