Megabox Cinemas Coex Mall

The Megabox COEX opened its doors with 16 screens and a 4,336-seat capacity on May 13, 2000, the same day the COEX opened its doors to the public. One of the opening attractions shown at the COEX was “Mission Impossible 2”, among others. The COEX is so successful that in July 2001, a record-breaking 30,000 people attend the theater in one single day.

As of October 2023, the COEX had a total of 19 screens, but only 10 of the screens are to the public. The largest screen being Screen 1 but its seating capacity was not the largest there in Screen 1 despite having Dolby Cinema installations as it had 378 seats. Screen 2 has the largest seating capacity of 432 seats. Screen 3 had 348 seats with CinemaScope proportions. Screen 4 had 332 seats, while Screen 5 had 281 seats with VistaVision proportions as well as a Mayer sound system. However in July 2021, a contract was signed with a fitness company and remodeled the screen into an indoor stadium but was restored back as a screen on May 24, 2022. Screens 6 and 7 had 285 seats while Screens 8 and 9 had 255 seats. Screen 10 (formerly Screen 11) had 166 seats, while the former Screen 10 had the same amount of seats as Screen 11 was demolished in June 2023.

Down below featured nine private screens. Three of which were Boutique Suites with a capacity of 32 to 36 seats. There are also two other screens nearby that were also listed as Boutiques but were located in the B1F section, all listing with 82 seats in both screens. Nearby is Screens A and B, which were all similar to the private sections of CHV Cheongdam Cine City. Screen A had only 36 seats, while Screen B had 30. And next to it are two private boutique screens. One only had eight seats and the other only had ten.

With that said, the theater (including the demolished Screen 10) had a total capacity of 3,535 seats. But since June 2023, it now has 3,369 seats. Its current functions are first-run and foreign features.
