Ninja Assassin is an upcoming martial arts / action movie directed by James McTeigue and starring Rain in the lead role as Raizo one of the world’s deadliest ninja. Below a teaser poster of Ninja Assassin from 2008 Comic Con in San Diego:

This poster of Ninja Assassin reminds me the Thai action movie Ong Back. But I think that Ninja Assassin will be more satisfying because besides a fight choreography there will be a real plot in Ninja Assassin.
