20 Things You Somehow Missed In Back To The Future Part 2
2. Biff's Curious Taste In Porn
Keep an eye on some of the "viewing materials" that alt-Biff has strewn around his penthouse apartment, because there's a bit of an odd theme to his tastes in pornography.
While Marty talks to Lorraine and takes in everything that's changed, two porno tapes can be seen around the apartment: "Black Taboo" and "Playing with Fire."
These might sound like made-up pornos, but they are in fact real, and odder still, they both have a pronounced incest theme. No judgment here, but isn't that the most on-brand thing imaginable for Biff?
It's an especially interesting choice given the obviously incestual implications in the original Back to the Future, what with a young Lorraine unknowingly having the hots for her own future son.
