This short film doesn't need to have a parody, because it is almost a self-parody.
It's Fassbinder's earliest work, according to the IMDb. The problem is that while watching it, I couldn't help but think of two "Saturday Night Live" scenarios: "Sprockets" and Leonard Pinth-Garnell's "Truly Bad Cinema." Honest. I was expecting Dieter to pop up at any moment from the midst of the bushes at any moment, and at the end, Leonard Pinth-Garnell to pop up, saying, "Truly, truly awful. A brilliant example of bad acting." About the best that I can say for this is that the photography is pretty good.
The only reason I can think of to watch this is for the reason I did so: to see some of Fassbinder's earliest work. I can't say that I'm upset that I spent ten minutes of my life watching it, but if it had gone on for another twenty minutes, I would have been waiting to hear Tom Servo's commentary on MST3K at some point.
