I remember watching a short film that was probably from the 40's or 50's. It was in black and white. I don't remember any names; just how the story goes. It wasn't aired on television when I saw it; it was during a high school class on a VHS tape.
It starts with an elderly man being honored for having traveled 100 years into the future 100 years ago to the day. The story implies that he was the only one to have done it and did it only the one time. When he came back he told everyone of a paradise society, and, naturally, 100 years later, that society was a reality.
The world was anxiously waiting to see his historic journey conclude. Many gathered around the area where his vessel was to appear from 100 years earlier. They waited up to the minute, but he did not come. Nothing happened. The people were bitterly disappointed and utterly confused. The society he saw was here; his story had been verified, but he did not appear. When asked what was going on, he confessed a different story than he told everyone 100 years ago.
He never did go into the future. He deceived everyone with essentially a magic trick and an a very convincing demeanor. He created the story so that the people would believe it then work to that end, which is exactly what they did. The paradise society became a reality because they were told that is what would happen. A self fulfilling prophecy.
What is the name of this short film? It should be in public domain by now, so if it is available on YouTube or somewhere else that would be awesome.
