So these people got to go to an advance screening of Thor: Ragnarok and instead were "treated" to a 4 D experience. The real cast were brought in to perform the movie in front of the screen. It is different but as Cate Blanchett mentions "I think they just want to see the movie." She would later say to her manager on the phone "I think this is a mistake." You decide be aware there are spoilers if You haven't seen Thor: Ragnarok. Do Not Be Looking For This At A Theater Near You Ever but it is interesting.
