I doubt they are used in movies much, if at all, but they are the only way that I can think of to have a live automatic firearm operate properly with blanks with no modifications.
Oh, plastic training rounds! Yes, those DO exist you're certainly correct about that. However I would fire any armorer that would see them used in a theatrical production!
