The Bourne Upchuck

Does this movie make you dizzy?

Continuing our discussion about the nauseating properties of hand-held, quick-cut, whip-pan, rack-focus camerawork, David Bordwell sends along this account of an unlucky filmgoer who saw "The Bourne Ultimatum" in IMAX:

We went to see "BU" on the IMAX in San Francisco. Near the end, when Webb is having the flashback to when he is forced to show his commitment to the project, the lady next to me spontaneously unleashes a huge amount of vomit all over my leg and all over the floor in front of her! I have never experienced anything like it in my life!

Now all the action sequences, the nauseating use of moving cameras, and the relentless score were enough to make anyone dizzy, but to throw up?
