Fans of The Hobbit certainly had an unexpected journey, with members of the audience at the world premiere feeling dizzy and nauseous.
Director Peter Jackson has shot the film at 48 frames per second — double the camera speed normally used — in an effort to sharpen up the 3-D effects.
However, it left one viewer complaining of a migraine and another comparing the experience to being on a rollercoaster.
“You have to hold your stomach down and let your eyes pop at first to adjust,” one viewer told British newspaper The Sunday Times. “This is not for wimps.”
The Hobbit: An Unexpected Journey opens on Boxing Day. However, most people will see the film in the traditional format as only a few cinemas worldwide are set up to show the 48fps format.
