#17: Polar Express
Like any classic Christmas film, the Polar Express takes us on a journey to find the North Pole along with our friends. But unlike other classic Christmas films, this one has something in common with a film that has absolutely nothing to do with Christmas.

The Polar Express and Back to the Future both use the same prop in their films. The Flux Capacitor from Back to the Future can also be seen in the Polar Express. Kinda random, huh? Well, Robert Zemeckis is the director of both films, and it seems like he wanted to have a little bit of fun.
