Saw this on a DVD in 2012. Plot- a group of people from different countries take an illegal tour to explore Hitlers special bunker through a labyrinth of tunnels, sewers and catacombs. The movie offers up a good amount of intensity and creepy atmosphere. The underground tunnels were claustrophobic and atmospheric. There was sufficient tension but the gore might put off some. The effects were well done. The pacing was good n the film never dragged. The direction, editing n cinematography were noteworthy. The villain is very intimidating. His glee at playing the hunter is so fierce that it wud disturb some viewers. His face is the most terrifying thing about the film. I wud rather take my chances n go alone than follow a creepy guy with that face. Klaus Stiglmeier, the guy who played the villain was more creepy than the guy from Wolf creek. My only crib is that the two sub plots, 1)The encounter with the nasty chaps n their vicious dog n 2)the story about Hitler's desire to build an army of super soldiers were never explored. There is something sinister about the neo Nazis n Hitler. Nevertheless it is a decent thriller. Fans of Creep - 2004, Wolf Creek, Descent n Stag nite will definitely enjoy this.
