My brother and I were watching Back to the Future III and he turned to me and asked "You think that little kid (the marshall's son) is the principle or his dad?" And I'm like "wait, what?"
I have seen this movie a million times and never realised that Marshall Strickland and Principle Strickland were from the same family.
It happens a lot with movies I saw first when I was a kid.
Which is your favourite Back to the Future? I like the first one pretty well, but the third is my favourite.
