For me it's any show or film that's supposed to be set on Earth far into the future, yet the characters speak perfect early 21st century English. If not a full conlang at least evolve the language a bit or add some new slang that creates more of a sense of future place.

I can report that as a director, it helps to stay out of the way and let the conlanger do their thing. When asked, I'd give feedback on what I thought about the aesthetics of the language and writing system, but I knew there were things that I just didn't understand about language and that it was best left to the expert...

In the film we tell the story of the first 'known' conlanger from the 1100's! Tolkien is the gateway drug for many young conlangers, and as far as I picked up in doing interviews for the film he's very highly regarded.

There's a story about exactly this in the bonus feature to the documentary - watch and find out... :->

We actually deal with this in the film, by both showing why people conlang and by highlighting examples of conlangers who ALSO help endangered languages!
