Why is there no remake?
This is a "lost" movie, but we have clips and a script. Why doesn't someone remake this, possibly incorporating the existing footage? It couldn't cost all that much to do, not it it was done using 1915 technology, etc. Probably any film student could do it.
So, Aspiring Film Maker, if you're reading this, the challenge is out. Remake "Der Golem" (1915). 'Kay?
