When Mack finally finds Lightning McQueen in Radiator Springs in the movie "Cars," he's talking a mile a minute. Yet, anyone listening closely will hear him say, "Thank the manufacturer, you're alive!" It may seem like a simple line to a kid watching, but any adult witnessing this will notice that it's a quick reference to religion. While they may only be cars, they still believe in something.

We all know that cars are made by a manufacturer, but considering no humans exist in the world of "Cars," the one responsible for making all of these automobiles must be a higher power. After all, where else would these talking cars come from?

When Slash Film asked the creators of "Cars" about this quick reference, they had a quick response, too. "We try not to go there. We just try not to go there," story supervisor Scott Morse said. "There's a surreal level of disbelief that you're having to jump already coming into the world where there are talking cars. ... We lean into that as much as we can and try not to get too hung up on the surreal nuts and bolts of it, I guess."
