Movie theater visitors in Los Angeles: prepare to be thrown around, blasted with air, and sprayed in the face with a fine mist. South Korean company CJ Groups 4DX movie technology — in which 3D film showings are augmented with wind, light, fog, water, and scent effects — is coming to a US theater for the first time this summer. The technology will be installed at Regal Cinemas LA Live Stadium 14 in downtown Los Angeles. 4DX technology is already present in theaters in other countries, including Taiwan, Bulgaria, Columbia, and its native South Korea, at a cost of between $1.5 and $2 million per venue.
