Filmed in 24 hours?

Supposedly this was filmed in 24 hours, and although it is very rough and almost student film like, it was completely entertaining and interesting to watch. I got to see this as part of the showing of this director's German Trilogy which showed here at the Museum of Modern Art. Although there were walk outs for all 3 of his films, this one by far had the most walkouts throughout the screening. German Chainsaw Massacre of course had the least, as a title like that would be a warning to anyone expecting high art. Terror 2000 had the quickest walkout, immediately following the first scene. I am always amazed at walkouts, no matter what I still want to see how it ends. Sometimes a film can completely change by the end. I remember disliking Takashi Miike's Visitor Q throughout most of the movie, it was only in the last 20 minutes when he wrapped it up in such an an amazing way that he changed my whole feeling about the story and its characters. I left the theater feeling joy and happiness for people who I was feeling mostly disgust and despair. Any director that can do that is well worth sitting through hundreds of hours of crap.
