I also frequented movie festivals.
Don't take this personally but I think you were at the wrong parties. Good signs to tell if you are "in" or not: do you know how to get illegal drugs on set? have you ever been to a private event in a hotel room or AirBNB before or after a ceremony? have you ever been in the same room with an A list celebrity or actor when they are using an illegal substance?
If the answer to all those is no then yeah it's probably that you are in the wrong parties.
If you've been there and like never witnessed a movie level epic orgy then that's great for you. I know they are not usual on some circles, I've heard Disney and Netflix try to keep their staff on a tight leash. Honestly I wished my experience was more like yours because I liked the industry and it was a little bit of a dream of mine to be more involved with the movie creative process, and one of the reasons I didn't get more into it was that I was not comfortable mixing illegal drugs and orgies with work in the way it was usual.
