Hallowe'en and copyright

Ernie sez, "On Halloween, what is more scary than copyright law? For example, did you know that the famous vampire movie 'Nosferatu' was almost lost forever due to copyright? On the other hand the makers of a Michael Myers Halloween mask won a lawsuit by proving they took the idea from the movie. Maybe someone can figure out how to get around pumpkin carving DRM. If not, some ghost pirates (or is that pirate ghosts?) have a solution for the file sharing problem."
