I saw that movie for the first time the other week (1936 - The World to Be or some-such name by Orson Wells. Very interesting movie.
I almost wonder if “The Walking Dead” isn’t modeled on it. Zombies, all the various warring tribes, a helicopter appears out of nowhere, a modern region unaffected by the turmoil....
Another thing. The movie, from 1936, obviously most folks knew that the world was almost at war again with Hitler. In the movie the war lasts for 30(?) years. Obviously the use of atom bombs messed up their view of the future. But a cool, foretelling movie.
BTW - many animals DO become zombies. Perhaps humans to a degree infected with rabies. I first pointed this out when the Walking Dead came on and my kids were young. My kids still remember me hearing about the show, and wanting them to watch it with me. “Yeah - we thought it was going to be another one of your lame shows. Who would have thought that we would be buying t-shirts, posters and going to Comi-cons!?” (Them - not me!)
