M. Night Shyamalan and The Village and Action Comics #324.

At the Mitch O'Connell Blog (via BoingBoing):

Almost 40 years before "M" came out with his film "The Village" about a hidden town of present day Amish-Like occupants of a small Pennsylvania village who are made to think it's really 1897, and kept secluded by the woods from venturing into the modern (evil) world, it seems Action Comics #324 had the same plot.

Of course, as any kidlit aficionado knows, he ACTUALLY stole it from Margaret Peterson Haddix's Running Out of Time.

But I'm always happy to see someone take a swipe at that movie, so whatever.
