The Viking era is getting gritty and very gory in Nicholas Winding Refn’s (Bronson) Valhalla Rising. Now the rather strange but definitely intriguing opening sequence of the film has been released, which is both violent and well worth watching. The film itself is about a mute, one-eyed Viking warrior (Mads Mikkelsen), who’s been kept prisoner by a Norse chieftain, but manages to kill his captors and escape, setting off on a boat into unknown waters. Valhalla Rising is set for release in the UK on April 30th. Be warned though, the clip below is only suitable for those over 18, as it is very violent.
