From the Kinja archive (9/14/16):
Who wants to see the legendary nine hour cut of Greed (1924)? Gone. Most of the silent era of movie history is missing. Some lost films have now been found. Sometimes still photographs, publicity materials, and contemporary reviews exist but the movie does not.

The First Men in the Moon (1919).
This film from 1967 is an unlicensed parody that sees the DC Comics hero, Batman face off against Dracula (something the official comics themselves have done a number of time). This Filipino film starring Jing Abalos as the caped crusader is one of the most sought after lost Asian films for vintage movie buffs.
