Movies get chaotic if watched on an iPhone

This Euro RSCG commercial for Canal+, a French pay-per-view channel, is exceptionally well executed, with the stars of the "movie" shown sliding around—the result, it turns out, of movements made by a person watching on an iPhone. But this approach takes on an unintentionally ironic twist given the issues surrounding the latest iteration of the Apple handset. Why, exactly, might users be shaking up the phone so much? Could it be … a signal reception problem? Nah, they're probably just sliding on that nifty free bumper case now available for no particular reason at the Apple Store.
