The Hobbit: An Unexpected Journey is set to hit theaters on December 14th. Some audience members at advance screenings are reporting nausea, migraine headaches, and general queasiness after watching it. The film was shot at 48 frames per second, twice the normal rate, to achieve an unprecedented feeling of reality. But that can backfire.
When you watch a film, explains Adrian Bejan, a professor of mechanical engineering at Duke University, your eye combines "long and fast horizontal sweeps with short and slower vertical movements to process the picture." But this faster camera speed "requires the eye to sweep up and down faster than usual in close-ups to absorb unparalleled detail on a big screen," causing a significant amount of cognitive and eye strain. This technique "works for the big snowy mountains, but in close-ups the picture strobes," said one moviegoer. "I left loving the movie but feeling sick." Another audience member was more blunt: "My eyes cannot take everything in, it's dizzying," he said. "Now I have a migraine."
