Is there a term &/or hashtag for when you see a film (or something related to one) in another film? E.g. in a film, the characters are watching a film on TV, or they pass a marquee/sign for another film.
For now, I'll use #FilmInAFilm & post an example: large painted sign for Michael Dudikoff war flick Platoon Leader (1988) in the background of action-comedy 賭神 (God of Gamblers)(1989)
