Korean remake. Genuinely terrifying film with great twist. Buy it if you dare!
The Univited centers around two teenage sisters Anna and Alex Rydell (Emily Browning and Arielle Kebbel) who return home from a mental hospital only to find their recovery unraveling because of a cruel stepmother, an ignorant father and a lingering, scary ghost. With their mental states deteriorating can they stay alive in a haunted house where the only thing they have is each other?
The Univited is based on Kim Jee-Woon's 2003 Korean horror film Janghwa Hongryeon which in turn is founded on a classic Korean folk tale.
