Continuity mistake: When Raimund pulls the girl with the red coat off the railing bridge, his briefcase opens and his pupils' essays fall out and get wet in the rain. Raimond and the girl pick them all up, but they are a mess; miraculously, when Raimond starts to put them back, they fit easily, and they are not soaking wet.
