Collin Chou (Matrix) told SCI FI Wire that he will be one of four leads in a new fantasy ninja film from "Matrix" creators Larry and Andy Wachowski, who will produce but not direct. Variety has reported that the film will be called "Ninja Assassin," a title Chou couldn't confirm.

"I don't think I'm supposed to talk about it, but I am working with the Wachowski brothers next month, and I look forward to working with them again on a major movie," said Chou, who played Seraph in all three "Matrix" films. "It will be in Berlin."

Chou also confirmed a longstanding rumor that he is playing a role that Jet Li turned down. "I have to say that I'm constantly grateful to Jet Li, and I thank him all the time, but that is personal," Chou joked.

Chou said that the Wachowskis' ninja movie starts production in late April or early May. "And this is a part that is built around me," he said. "They have wanted to have me in a larger part, and I was waiting and waiting for a long time for it to happen. I am one of four of the main characters in this movie. It is a great honor to be on board."

Korean pop star Rain, whose real name is Jung Ji-hoon, is also part of the project and one of the four main characters. Rain, who is in the upcoming "Speed Racer" film, was also in last year's Korean film "I'm a Cyborg, But That's OK."

Variety earlier reported that the film will be produced by "Matrix" producer Joel Silver and most likely will be directed by James McTeigue, who also helmed the Wachowski-produced "V for Vendetta."
