A theory about the film Back to the Future

You've seen the movie Back to the Future. Have you ever thought about the story from the point of view of George McFly (Crispin Glover)? Imagine what you would think if you had a son who, as a teenager, began to look *exactly* like the guy your wife dated before she dated you?

I think the entire movie takes place in George's mind. He can't deal with the obvious, but unthinkable, explanation: that his wife Lorraine (Lea Thompson) had an affair and conceived a child with ... what was name of that guy she went to prom with? Oh yeah, "Calvin Klein".

Instead, he imagines that his son Marty (Michael J. Fox) took must have traveled back in time. Calvin never even existed. It was Marty all along and, under a fake name inspired by his underwear, he was really helping George get together with Lorraine.

George is a science fiction writer after all. I wonder how close this is to the plot of "A Match Made in Space".
