Universal Pictures has released the first trailer for the 3D action-adventure title ’47 Ronin’ starring Keanu Reeves, Hiroyuki Sanada and Ko Shibasaki. The film was directed by Carl Rinsch with a screenplay from Chris Morgan and Hossein Amini.
In the film a “treacherous warlord” kills the master of 47 Ronin, banishing their kind forever. Soon the 47 leaderless samurai vow to “seek vengeance and restore honor to their people”. Universal describes the film in a press-release stating, “Driven from their homes and dispersed across the land, this band of Ronin must seek the help of Kai (Reeves)—a half-breed they once rejected—as they fight their way across a savage world of mythic beasts, shape-shifting witchcraft and wondrous terrors.”  
As mentioned above the film is led by Carl Rinsch (The Gift), 47 Ronin is produced by Scott Stuber (Ted, Identity Thief), Pamela Abdy (Identity Thief, upcoming Endless Love) and Eric McLeod (Mr. & Mrs. Smith, Austin Powers series).
