While Doc and Marty’s Back to the Future friendship is famously strange, any familial link between the pair would have made the trilogy much creepier. As standup comedian John Mulaney noted in his 2015 special The Comeback Kid, Back to the Future has a pretty odd premise. While the adventure comedy is now seen as a classic sci-fi hit, Back to the Future’s storyline still sees a young man travel back in time to intervene in the budding relationship of his future parents, and one of the movie’s biggest laughs comes from his unwitting mother’s attraction to her own son.
