We all love movie theaters for the special feeling they give with fantastic special effects, complete sound immersion and the taste of popcorn. Would you still love them just as much if you found out their secrets movie theater owners don’t want you to know? We’re going to unveil 10 movie theater secrets. In cinemas, many people can’t always keep their feelings to themselves and that’s normal. For example, a movie about cannibals called Raw appeared to be too hard to watch for a couple of visitors at The Toronto International Film Festival in 2016. The people fainted and one of them hit his head badly during the fall. Digital devices can do everything on their own, and there are more automatic processes at a cinema than there were during the previous century. Keep it in mind that in case there are some problems with a projector (the image is blurred, not centered, etc.), you’ll have to stand up and go notify a staff member in the lobby. 20% of the population, including Johnny Depp himself, simply can’t perceive those three dimensions. Harvard Medical School neurobiology professor Dr. Margaret S. Livingstone explains it could be due to stereo-blindness when eyes can’t see in 3D because of the way they are aligned. If you love cleanliness that much, try to visit the cinema in the morning and avoid going there on Friday and Saturday nights when a lot of other people go out to the movies.
