okay, i noticed everytime the new trailer (french) is up the authors claimed about the video rights and stuff but isn't normally when आप tape it 'your video', so why do they keep doing that :(

I don't understand lawyers and all their rules.

But you've got to understand that it is footage owned द्वारा them, whether someone else records it या not. I can't give आप a good reason for them wanting to मिटाइए it, but obviously it's a marketing strategy. The संगीत companies do it all the time, even if only 5 सेकंड्स of their song is used in a video, they still have the rights to get a यूट्यूब administrator to take it down.

My only guess as to why they would मिटाइए the trailer is to get आप so hyped up (without any spoiler footage या extra scenes) that आप wanna see NM even और than आप did before (meaning another प्रशंसक buying tickets, equalling और money). It's very stupid when आप think about it, but obviously it works when आप look at it from a business angle, या else they wouldn't be doing it.
Do I agree with their methods? No. Do I think they're greedy jerks? Yes. Anyways, there's nothing आप can do except watch the vids before someone flags them and they get deleted :/
