If Kinski agreed to do a film, the most important thing to him was the money. At least this is what he says. His autobiographies (there are three in total) present him as the weird, nervous, sexually obsessed genius that he wanted people to think of him. Although it is well known that most of the dramatic stories Kinski tells about his life are made-up (e.g. most of his struggles with long-time director Werner Herzog), others are near to the truth. HAINE, for instance, proves that Kinski did in fact not care about anything but the money, at least in the present case. When the filming days he was contracted to were over, he simply left. This is why the director had to case someone else play Kinskis role, which was wisely chosen as a motorbike driver, thus the stand-in wears a helmet in all of its scenes; including some in which hardly anyone would wear a helmet... Oh, and Maria Schneider is in there as well, even with some nudity. I presume on paper the film may have looked different than the final product. However, if you like exploitation and an exaggerated storyline and a bit of sleaziness and, most of all, Kinski, there's doubt you will enjoy the film.
