Will aliens and zombies rampage through these ancient stone causeways, forcing Israelis and Palestinians to turn their weapons against a common foe?

To judge by an Israeli-sponsored competition of animated short films envisaging Jerusalem a century hence, things won't go easier for the city at the heart of the Middle East conflict.
