1UP took note of a tiny blurb in Japanese magazine Kinema Jumpo, which indicates that Namco Bandai is preparing a Tales of Vesperia movie. The animated film will allegedly be the first in the series to hit the the big screen. Tales of Phantasia, Eternia, Symphonia and Aneurismia (not real) have all received linear animated media releases, but not in theaters.
The Japanese version will feature voice talent from the game, but there's no word if the same is planned for an international version. 1UP speculates that the film could be used to cross-promote a PS3 version of Vesperia. We don't know about that, but Namco Bandai did eventually take its Xbox 360 exclusive, Eternal Sonata, to the PS3.
