What it’s about
Colony (2026)
Professor Se-jeong is thrust into a bloody nightmare when a rapidly mutating virus is released during a biotech conference causing authorities to seal the facility. Trapped inside with no escape, Se-jeong along with a small group of survivors must fight to stay alive while the infected undergo horrific transformations.
The same weekend also brings The Last Sunrise. Two trailers, one argument about which one wins the window.
Colony opens in theaters on August 28, 2026.
