It's clearly impossible to end up with a white haired man and a Delorian from the words "Back to the Future", so it likely has way, way more information about the movie than the title. Possibly even movie posters. I think it's a bit misleading.

The training set could have included images from or related to the movie? It's a cult classic, so it does not seem entirely unlikely to me.
