The adventure manga author Akira Toriyama confirms in the 33rd issue of Weekly Shonen Jump magazine that the upcoming Dragon Ball Z anime film will be a part of the official Dragon Ball story.
The new film will took place right after the final battle against Majin-Buu (Chapter 517: A Happy Ending... And Then...), and before the 10 year timeskip (Chapter 518: 10 Years After). It was considered as the manga, and anime's "lost decade". Krillin, Piccolo, Vegeta, and other familiar characters will appear in the film.
The film will be directed by Masahiro Hosoda (Dragon Ball Z episode director) at Toei and written by Yuusuke Watanabe (20th Century Boys, Gantz), with Tadayoshi Yamamuro (Dragon Ball Movie 4: The Path to Power, Beet the Vandel Buster) acting as the lead animation director. Manga author Akira Toriyama will be deeply involved in the production.
The film's production committee includes Fox International Productions Japan Shueisha, Fuji TV, Toei Animation, Bandai, and Bandai Namco Games. It will be slated for March 30, 2013 release.
