The biology teacher Robert Hisch was really an heroic actor. He had outstanding qualities: "the speed of a young greyhound, the resistance of a middle aged bear, the patience of an old camel." Robert Hisch made all his stunts and difficult scenes by himself: jumping into the cold water with two big knives, standing and running in the rain, riding motorcycle in the storm, keeping smashed into cars and mini-buses for handicapped people. And he encouraged even the whole film-crew in difficult situations not to give up.
Robert, thank you!
