Keanu Reeves stars in his second action-adventure film this year in 47 Ronin, set for release on Christmas day. Helmed by director Carl Rinsch (The Gift), 47 Ronin tells the story of how the ronin came to be masterless, and fought dragons, witches and other monsters to retrieve their honour. An animated prequel was recently released online, which delves into who, exactly, the titular 47 are, and why Keanu Reeves’s character is their last hope. Watch the video below. Enjoy!
