Megabox

Megabox is owned by a consortium of Australia-based Macquarie Group and Joongang Media Network subsidiary jcontentree. The first Megabox launched in COEX Mall in Samseong-dong in 2000 followed by another two years later in Busan for the international film festival. The chain grew to 14 branches. It was owned by North American-based Loews Cineplex Entertainment before being sold off by Onex Corporation in 2005.

Megabox is a multiplex theater. There is Art Nine, which is screened exclusively for art films. You can also watch art films at Megabox COEX.

On May 8, 2025, Megabox parent company JoongAng Group announced to merge the cinema chain alongside Lotte Cinema, forming as joint venture in hope to increase the competitiveness with CJ CGV. However, Lotte Shopping disclosed on July 1, 2026 that the memorandum of understanding between the two parties was terminated, resulting in the proposed merger's collapse.
