Awesome ! First saw this a few years ago. It took them $30,000 to make, and the Joker was played by Walter Koenigs son (Walter being Chekov from the Original Star Trek series).
There is a website that has a bunch of info on short independent films like these, some quite good, if I can remember it I will link it later. On E-bay I actually ordered this batman movie along with a few other superhero chort clips on one dvd (like the Grayson one that was mentioned--which is pretty good too)
This short clip is just outstanding, just awesome with the Predator and Alien both involved.
Having been a BIg Batman fan for 40 years (Even have a few costumes of my own, and I even made a small time batman video myself back in 1990 on a very modest budget of a couple thousand dollars), I can really appreciate this "Batman: Dead End" short movie.
OUtstanding, just Outstanding !!!
