Collin Chou, who played the Seraph in the Wachowski's Matrix trilogy, has confirmed that he'll be starring in a fantastical ninja movie to be produced by the Wachowskis. He couldn't say much about it, but did admit it would have fantasy elements and that production is set to start next month. Korean pop singer Rain, who most recently played a cyborg in I'm a Cyborg But That's OK, will also be in the flick, rumored to be called Ninja Assassin. [Sci Fi Wire]
