How Old Back To The Future’s Cast Was Compared To Their Characters

The ages of the cast and characters in Back to the Future are a bit convoluted, given that the movie takes place in two different timelines and some actors play their roles as teenagers and adults. The science action film premiered on July 3, 1985, and depicted a teenager accidentally traveling back in time (to 1955) via a DeLorean time machine that his older scientist friend built. Unfortunately, while there, he accidentally interferes with the timeline and threatens his own existence when he comes across his parents as teenagers.
