CJ 4DPLEX’s 400th 4DX location launched earlier this week at Wanda Cinemas in Beijing, China with a screening of Spider-Man: Homecoming – an ideal showcase for an innovative film technology that features motion seats and environmental effects such as wind, rain, fog, lights, and various scents.

CJ 4DPLEX has announced that its 4DX technology is now available in 400 theatres around the world. The opening of its 400th location in Beijing makes 4DX the fastest-growing premium cinema format, having reached this milestone in seven-and-a-half years following its debut in 2009.

The 400th 4DX location launched earlier this week at Wanda Cinemas in Tiantongyuan, Beijing, China with a screening of Spider-Man: Homecoming – an ideal showcase for an innovative film technology that features motion seats and environmental effects such as seat motion, wind, rain, fog, lights, and various scents.

With this opening, more than 49,000 4DX seats have been installed in theatre auditoriums across 49 countries, with the capacity to accommodate more than 89 million worldwide moviegoers per year. This number is due in part to an accelerated growth rate that has led to more than ten new 4DX sites opening per month for the past ten months, with the number of worldwide locations growing from 300 to 400 in record time, topping the 12 months it previously took to grow from 200 to 300.

“Launching our 400th location at Wanda Cinemas has significant meaning for us, and is a testament to being the fastest-growing premium cinema format. We plan to build on this momentum and continue to thrive worldwide, with the goal to be the leading premium cinema brand in the global cinema industry in the coming years,” said Byung-Hwan Choi, CEO of CJ 4DPLEX. “We look forward to seeing sustainable growth in the global market as we build solid partnerships and maintain reliable relationships with our exhibitor partners.”
