The Yatterman website has been up since last summer and there’s yet to be a trailer on there, but atleast there’s some content on there now. You won’t get much information if you can’t read kanji. The film should be finished in 2009.
Yatterman is based on a 1977 anime focusing on a time/space pursuit between heroes and villians. A remake of the show has been airing in Japan since January and the film will have Sho Sakurai from Zebraman playing Gan Takada.
