Maybe it was something I realized last weekend, when posting that Back to the Future YouTube link - the movie, which I still think is a perfect little thing, was made in 1985. Marty was sent back to 1955. If they made the movie today, he’d go back to 1977.
Think about that. 1977 would look like today, minus computers. Same clothes, same Pink Floyd tunes on the classic rock station, same smear of gimcrack commercial architecture interspersed with stalwarts from the 20s. Color TV, Star Wars, angry Iran. Marty could order a Pepsi Free in 1977, and they’d think it was a sugarless brand they hadn’t gotten yet.
BTTF was an iconic movie for me growing up in the 80s, and its timeline transposition from 1985 to 1955 placed me inside a world I knew nothing about. Thinking that the same transposition today would make me 8 years old is a bit of a shock.
