Winterschläfer is the film director Tom Tykwer made before Lola Rennt. I like this one better than Der Krieger und die Kaiserin, but not as much as Lola Rennt. The film is beautiful. Stunning landscapes. Lush sets. Beautiful people. The plot is interesting, but ultimately doesn't have a huge amount going for it. The film examines the lives of René, Laura, Marco, Rebecca, and Theo after a car accident where Theo's child is killed. René had stolen Marco's car in a drunken stupor and doesn't remember. Later, when he meets Marco, Laura, and Rebecca he slowly pieces things together. Tykwer throws in coincidence that doesn't really mean a lot, which is refreshing. Most directors put in coincidence as if it means everything. Tykwer seems to know that it doesn't, but still ties everything together anyway.
Also, this is where Memento stole the memory gimmick.
