I want to talk about something I have trouble finding a name for, that I could then use to mean both parody scenes and homages. If possible as well things like cameos, hidden nods to prior works, small items in the background that were used in other works, catchphrases from other works, posters, scenes playing on a TV, characters talking about and so on and so forth.
More or less the act of referencing other media or "culture" within something like a movie. But not the word reference itself, that's too generic.
Edit: About a sentence where the word would be used: that's difficult. You'd say "X is a [parody] of Y" or "X is [paying tribute] to Y" or "X has a [cameo] from Y". All those sentences are different and since I don't know the word I'm looking for, I can't provide a sentence that would work.
But it will end up as a headline and should be a word where everyone immediately knows I'm talking about entertainment media.
Words I've considered (definitions from wiktionary.org):
allusion: "An indirect reference; a hint; a reference to something supposed to be known, but not explicitly mentioned "
It doesn't carry the association with entertainment media, though. I'm also not entirely sure if it can be used in this context.
testimonial: "A tribute given in appreciation of someone's service etc."
The word itself has little to do with the actual concept I'm going for and doesn't really fit, since it's not used in this context as far as I know. But starting to use it for this could work. Or maybe not..
