Overview
- Well Go USA released the official U.S. trailer on June 30, 2026, which reveals a rapidly mutating virus and an information‑sharing, hive‑mind type of infected.
- Distributor and press materials list a U.S. theatrical release date of August 28, 2026, and the film carries an R rating for bloody violent content and some language.
- Colony stars Jun Ji‑hyun, Koo Kyo‑hwan, Ji Chang‑wook, Shin Hyun‑been, Kim Shin‑rok and Go Soo and is presented by Showbox with production by Wowpoint and Smilegate.
- The film premiered in May 2026 in Cannes’ Midnight section, where critics praised its high production values but gave mixed assessments of how it compares to Yeon’s earlier K‑zombie work.
- Yeon’s return to infection horror positions Colony as a potential tentpole for Korean genre cinema in U.S. theaters and makes box office and wider critical response the key measures to watch this fall.
