Launched in 2009, the experience didn’t secure a permanent foothold in America until 2014 with a theater in downtown Los Angeles. It’s been a long road from 4DX’s South Korean roots to Las Vegas. Instead, we’re supposed to make do with something called The Bottom Shaker. Yet, when CJ 4DPLEX unveiled its 4DX movie machinery Friday inside Auditorium 4 at Red Rock Resort - equipment that includes seats that move in sync with the film while air blasts your head, fog rolls in and, for some reason, water pelts you during rainy scenes - there was no Bottom Tickler.Īpparently that’s an option that theater owner Regal declined. If ever there were a city that should have been able to support such a thing, it’s Las Vegas. But it’s cutting-edge technology, nonetheless. Or the title of one of those true-crime movies on Lifetime. Sure, it sounds like the name of a D-list supervillain. Seats in Red Rock Resort's 4DX movie theater come four to a pod and move as one as they pitch, roll and heave in time with the movie.
