UPDATE: DRAGONBALL

Christina Inman clarifies some doubts about Dragonball
I have been in touch again with the manager of the Fox in Mexico, Christina Inman, and has clarified that you have some doubts regarding Dragonball.
- Release Date: April 8, 2009
- It can be taken as official and that date is set in stone.
- Sequels
- We will soon be addressing this hard and rush to finish the post-production of the first movie … Talk about second or third movies is premature.
- Trailer, website and official photos
She tells me that it’s likely that the promotion of the film start the second half of this year, because they are preparing several things … But she says that the worry is that the first film is well.
Teaser trailer-in “The Happening”
On whether the teaser trailer could emerge in the movie “The Happening” (13/June/2008), she commented that targets are different, and the classification of this film with Shylaman does not help that you can build there, so would be another movie for release … But perhaps for those dates there can be and will have some teaser.

"Dragonball" sequel to start filming next year?
Thu, March 27, 2008 (2:09am EDT)
Cinema Today reports that the second live-action "Dragonball" film may start shooting at the end of the first quarter of 2009. Previous news reports indicated that "Dragonball" has been planned as a trilogy, and now it seems that the next two films will be shot in Durango, Mexico, just like the first one. In fact, some of the sets were left in place even after filming finished. The first installment of the trilogy is scheduled for release on April 3, 2009, though Japan will reportedly get it first in March.
