4. “Mother!” (2017)
Ohh, this one’s fresh! In fact, it’s so fresh, I haven’t actually watched it, but I know what’s going on. I mean, it’s a film of Darren Aronofsky, which already says a lot, but I guess the movie trailers screwed things up. While people were expecting some supernatural horror-ish drama, they got something completely different. That would definitely make me walk out, especially after that baby-eating scene.
5. “127 Hours” (2010)
How on earth could a biopic make people sick and leave the cinema? Seems like an extra-long and incredibly realistic scene of amputating someone’s arm did the trick! This very scene (that I’m not going to show you) caused numerous panic attacks, and in some severe cases vomiting and fainting.
