Unfortunately what is considered the world’s first movie is A Trip to the Moon from 1902, so there exists no movie from 1873

It’s the licence plates from back to the future.

We actually did loop in Denmark a decade or so ago. It was quite easy to guess the production year of the car by just looking at the first two letters. It was a bit trippy seeing new cars with "AA 11 111” all of a sudden when we ran out of ZZ’s.

“We stopped using those years ago, gramps.”

And here I am wasting my money on 24 TB obsolete HDDs when I could have just bought SSDs.
