Fritz Muller-Scherz, who wrote the script with Fassbender, said that both of them knew nothing about computers at the time. "But we are very interested in this topic. If computers can simulate the artificial world, then the so-called real world. Does it exist?” Although science fiction themes were a bit of a surprise to Fassbinder, in fact the themes of independence, exploitation and control in the film multiplied with his previous works. “It’s just that "Circuit World" got rid of interpersonal The text takes place within a larger universe".
The film invested 300,000 US dollars, which is considered a big production by Fassbinder, but he was also shooting "Ali Fear Eats the Soul" and other films during the 44-day shooting period . It was mostly shot in Germany, but like Godard's "Alpha City", it also uses modern Paris as a hint of the future world. Fassbinder, who did not care about the image itself in his previous works, started the collaboration with the photographer Ballhaus from this film, and brought to the extreme his love for mirrors inherited from Douglas Sigg. The faces and bodies of the characters It is constantly reflected by various mirrors. Fassbinder, who is known for his uncompromising, pursued perfection on the set as always. "I always have my own ideas," Ballhaus recalled. "He often listened to it and came up with a better one."
Fassbender did not put this film on his list of his ten best works, but it still has a certain place in his mind, in the "In a Year of 13 Moons" dedicated to his dead lover . Fassbender described a scene that was cut off. The protagonist shed tears after reading a novel about parallel worlds. The title of the book is exactly the title of the film. In 1981, the last time Fassbender saw the film starring Lommel, he expressed his hope that the film would be shown in theaters one day. This wish was not fulfilled before his sage.
