Joseph Gordon-Levitt stars in the new  biopic of tightrope extraordinaire Philippe Petit The Walk, which opens in theaters today. Unfortunately, people have been throwing up and having a hard time to get through the ending of the movie.

During a press screening of the film, multiple audience members reported feeling "legitimate physical illness" when walking Gordon-Levitt walk the tight rope.

The reason this craziness is going on is due to the 3D effects and the depth of the way tightrope scenes were shot. A Mexican film director tried to explain the reasoning for the weird, anxious feeling -- "I felt a knot in my stomach. It’s like my head was reeling but I was not dizzy. The audience got a fear of him falling. It’s like actually picturing in your mind him falling. You really get a sense of depth."
