Saito twins vs. the World

This is not about Pi, but I have no other place to write about it :P

So, there is this poster on bus stop near my house, about some not-really-my-type movie. Somehow there was something familiar about it... But I didn't pay much attention to it.
Today, I went to buy a bread and was passing by this poster again, this time it finally hit me!

Can you see?


Shota and Keita Saito!! :D

I'm sure you know at least one from dramas Byakkotai or Gachibaka (with Massu).

Another movie poster that I found on internet:


I don't care about the movie, but it's awesome news!! :D Why they appearance in worldwide movie came by so quietly?! There even no mention about it on they wiki pages :(
