Corrected entry: Anyone notice how many spirals there were in this film? First, Manni is in a phone booth in front of the "Spirale" cafe, then Lola is running down a spiral staircase, the cameras are always spiraling around the characters, during the flashback of Manni and Lola in bed, there are spirals on the pillow, and many many more. Also, the film is a spiral, going back to the beginning and starting over.
Corrected entry: The red ambulance with its siren going is in all three sequences. We learn in the third one that it is carrying Mr Meyer, who was just hurt in a car crash, to the hospital. However, the car crash didn't occur in the first two sequences, so Mr Meyer wasn't hurt. So, why is the ambulance in the first two sequences?
Corrected entry: At the end when Manni gives Ronnie the money he got back from the bum, some money would have been missing because the bum bought a bike and some other stuff with it. Manni says earlier that "Ronnie notices everything," so wouldn't he be worried that Ronnie would notice the missing money? (01:14:35)
