When in doubt, some folk like to go full on hyperbole. Hence the use of the ”plagiarised” which is this case is 100% wrong.
@InTeCredo to plagiarize something is to take something and pass it off as your own. The Producer of La Famille Bélier
ALSO produced CODA - and he wanted to do it with Real Deaf Actors and not well known hearing actors (as was the case for the ‘original’).
Please explain how that fits in with your highly hyperbolic use of the word “plagiarize”? I assume you didn‘t know about the producer and his feelings, and therefore just created some random nonsense in an attempt to make a point (and fail),
