This "thriller" has a wandering yet fittingly weird plot, but the film sets the role of acting (and the lines actors are given to work with) into unusually high relief. A laconic loser whose expression almost never changes (with perfectly greasy hair) is coupled with a younger, fun-loving guy very much NOT of the overdone stoner-dude type that populates so many American movies. It takes a lot to worry this childlike "man," and the actor is possessed of a sweet, rubbery face of infinite expressiveness that makes the story a true joy to watch. For example, the transformations that flicker across his increasingly lustful countenance as a hot babe talks about sex are a wonder -- this is method acting at its most delightful. He's got a metal plate in his head that makes it bullet-resistant, which could have been cartoonish, but is somehow just right for his character. He's a 33-year-old (my guess) who never left junior high. His companion pulls his weight in the other direction with his world-weary ennui (not to mention boredom, anxiety and flickers of intelligence and terror). It's weirdly fun to watch an occasionally very suspenseful movie carried along by two such un-German Germans (to those familiar with Germans as they're usually portrayed). I was very entertained by this film.
