But I'll check this out. Looks interesting.
You are absolutely right. But well his name alone would generate the needed revenue for the film so they wont really heed Strey's concern.

If you're an old manga nerd like me, you may remember a series that came out in the early seventies called Ashita no Joe. It follows the adventures of Joe Yabuki, an orphan who meets his future after running away and bumping into a man named Danpei who will eventually train him to become a boxer. The series was extremely popular, spawning both an anime series and several videogames.
ANN has reported that it will be turned into a live action film, starring one of my own favorite j-boys, Tomahisa Yamashita from NewS, in the starring role. It seems he is undergoing vigorous physical training for the role. I know Japan is going to be really excited about this because of how beloved this series is, but all I can say is that I can only imagine Yamashita is going to have his shirt off for at least half the movie. And that is good freaking news.
