Believe it or not...
MMM actually gave people motion sickness in the theatre when it was released due to the use of the handheld camera through most of it; years later the same thing happened with THE BLAIR WITCH PROJECT (though the jostling, handheld camera was much more extreme). Both times (saw them at the same theatre) an employee was cleaning up vomit on the stairs.
No bulls**t.
