Here's the trailer of the upcoming Nintama Rantaro film called, Gekijō-ban Anime Nintama Rantaro Ninjutsu Gakuen Zenin Shutsudō! no Dan which will be released in Japan next year.
After that a live-action remake (The teaser at the end of the trailer) of the said series will be released next Summer that will be directed by Takashi Mike (Yatterman, Crow Zero).
The word, nintama was derived from "ninja" and "tamago (egg)"... and it was aired here in the Philippines as Ninja Boy Rantaro. O_O Mistranslation!
