In Back to the Future Doc states he could go back to 0000 to witness the birth of Christ. Thus this film is clearly about time travel.

Christopher Lloyd is best known for his role as Emmett “Doc” Brown in Back to the Future. His wild hair and over-the-top expressions have become the face of some of our favorite memes, truly making the actor timeless in his role as a pop icon. Who would have thought that Lloyd had some political connections with a former vice president as a doppelgänger?

As the 7th American vice president, John C. Calhoun worked under former President John Quincy Adams and then stayed on to work under President Andrew Jackson. He and Lloyd share a distinct look, especially when the actor was in character as Doc. The two share intense bulging eyes, some wild hair, prominent ears, and a long face!
