In your example it sounds like they called up the actual producers and asked first before showing it.
And they aren’t a publik skool.
I called the producers. I managed training staff and they had the film on large reels.
I said do you have permission in writing. No.
Coincidentally I had watched the movie it may have been part off the Police Story series, but it was 2 hour made for TV. We were doing negotiator training in those days.
The company name was on the start of the film.
