This clip is an excerpt from the French documentary film "Otaku" by director Jean-Jacques Beineix from 1994. It appeared dubbed on German TV some time later, which is the version you are seeing here. It has, to my knowledge, never been released in English. The subtitles are my own. Content is the intellectual property of the original rights holders.
