In 1985, Back to the Future was released in theaters, and instantly became a generation-defining film - but it almost never made it to the big screen. The major film studios rejected it countless times because, in many ways, the screenplay appeared fatally flawed. How did this zany, sci-fi flick manage to break the rules of cinema storytelling and resonate with audiences of all ages? It may be because Back to the Future is a parable; one that teaches us a lesson about how we view ourselves, and how we think about our future.
