5. Lone Pine Mall
Some people thought that they saw a mistake toward the end of the original ‘Back to the Future.’ They saw an example of brilliant continuity. Marty’s adventures begin beside the Twin Pines Mall in his hometown. However, when he returned it was now the Lone Pine Mall.
But this is a subtle nod to the fact that he crashed into a farmer’s tree during his time travels. It’s easy to forget about but the writers remembered. This is one of those great hidden movie details that make fans appreciate how much effort is put into filmmaking (via Joe UK).
