There’s a new Dragon Ball Z film coming out in 2013 co-written by Akira Toriyama!
The film will be animated, not live action.
The movie will take place at some point during during the 10 year break after the Majin Buu Saga of Dragon Ball Z. It will be written as part of the official timeline between chapter 517 and 518 of the manga.
The script will be co-written by Akira Toriyama, who has never been so deeply involved with the animated portion of his series before.
Some of the other main talents involved have previous Dragon Ball experience, including director Masahiro Hosoda, who directed some episodes of the Cell Saga in DBZ.
The main screenwriter is Yusuke Watanabe (Live Gantz, 20th Century Boys 2) and the main animation director is Tadayoshi Yamamuro, who has worked on Dragon Ball before. It looks like it will be animated by Toei, as expected.
