Here is a list of some of the best amateur fanfilms that I have come across on the web.
1. Batman – Deadend:

This is the best superhero fanfilm that I have come across. Features the Dark Knight taking on some of the most famous movie villains. Better than most of the commercial flicks. Made by Sandy Collora for about 30K.
2. World’s Finest :

Also made by Sandy Collora. Features Supes and Bats together against Luthor and Two face. The 4 minute trailer is great. It is so good that I actually wish they would let him shoot the whole movie.
3. Grayson :

Director John Fiorella makes Robin ultra cool in this 5 minute trailer. The setting is after the death of the Dark Knight. Robin comes home to take over and avenge his mentor.
