Wachowski Brothers getting underway on 'Ninja Assassin'

With their Speed Racer movie ready to release on May 9, the Wachowski Brothers have already turned their sights to their next project, Ninja Assassin, starring Korean star Rain. The English-language ninja film, set to begin production today in Berlin, will be produced by the brothers and directed by Wachowski protege James McTeigue (V for Vendetta). "The ninja scenes in Speed Racer gave us the idea to do Ninja Assassin," producer Joel Silver said at the Speed Racer premiere. "I've wanted the brothers to do a full-on martial arts film for a while now, but nothing ever came up. Then we were watching the first dailies of the fight scenes in Speed Racer and they looked at Rain in a whole new way. He's unbelievable as a fighter."

Silver would spill few details on the plot of the film, but we could glean that Ninja Assassin is a revenge-type story and Rain plays opposite Naomie Harris, best known as Tia Dalma in Pirates of the Caribbean: At World's End. "She plays the girl, the beautiful girl who also kicks some butt," Silver said.

Rain, also at the Speed premiere, was equally mum on the details. "They keep telling me that it is very secret and not to say anything about it. I play a ninja and I'm going to fight a lot is all I can tell."  (With reporting by Carrie Bell)
