A new movie poster and trailer dictates that Persona 3: The Movie will release in Japanese cinemas on November 23, 2013.
The movie’s official website contains quite a lot of information, including character biographies on all the characters involved. The site also suggests that Persona 3 is just the first movie of a series of productions but does not reveal how many movies will follow.
The movie was first announced in June of last year during the final scene of the Persona 4 The Animation: The Factor of Hope film. The video game though was released in 2007 for the PlayStation 2 and then again for the PlayStation 3 and PSP recently.
A debut trailer can be seen here but it is in Japanese.
