Here's a scenario for you all to consider. I've criticised my current Audible read in a previous entry, but it does provoke some thought.
The woman, originally from the C20th, has been transported (somehow) to the C18th.
The man is, and always has been, of the C18th.
The tale is set in the C18th, when they are also married to each other. Bear with it.
They're having a row. She snaps at him, "why d'you always want to behave like bloody John Wayne?" Obviously, the response in "who's John Wayne?"
Think about it. To try to explain movie star, you first have to explain movie. You probably then need to go back to still photography, how an image can make its way onto a piece of film...
What a nightmare! 🤣
