This is a theory that I had previously debunked in the past, back when I knew little about proper Creators/Movie Pilot format. But now, over time, I think that this theory could be plausible.
So Here's The Theory!
Many people have wondered how Lorraine and George in 1985 didn't notice that their son, Marty, looked a lot like Calvin Klein, who bought them together in 1955.
However, the theory states that George DID know about Marty traveling to 1955.
First off, George is a huge science fiction fan and this was to the extent that he actually believed that Darth Vader from planet Vulcan came to his room.
And if you add the fact that he knows Marty has a scientist friend, Doc, then he could easily think time travel is possible.
But think about what Marty said when he went in George's room. "My name is Darth Vader! I am an extraterrestrial from the planet Vulcan!" Darth Vader is from Star Wars and Vulcan is from Star Trek, two franchises that had not come out in 1955.
Marty also plays "Johnny B. Goode" by Chuck Berry, a song that was released in 1959, four years after Marty performed it.
You can say Lorraine also heard it, but along with the Star Wars reference, George also heard Marty order a "Pepsi Free", a soda that also had not come out in 1955.
However, George likely didn't tell Marty about it in order to avoid messing up the future. We later see that George's first novel is based on what Marty did in 1955.
And that's it!
Do you think George knew?
