Glasshouse review – dreamy dystopian horror with a Picnic at Hanging Rock vibe

A mother and her daughters hole up in a Victorian conservatory, hiding from a devastating pandemic that lays waste to human memory

Shot in a Victorian hothouse in South Africa with a mixed cast of local actors and the odd imported Brit - including Jessica Alexander, soon be seen in Disney's live-action The Little Mermaid - this tense dystopian horror-thriller feels geographically non-specific, almost as if it were taking place in some kind of dream world. That touch of hazy vagueness is just right for SA director and co-writer Kelsey Egan's cracking feature debut (co-written with Emma Lungiswa De Wet) which imagines a family of survivors hiding out in the title's botanical conservatory after a pandemic has ravaged most of the world's population.

The invisible threat here is an airborne virus called the shred" which wipes out memories and leaves its victims in a bestial state, unable to remember even their own names. A matriarchal woman known only as Mother (Adrienne Pearce) guides her three female progeny - cautious Evie (Anja Taljaard), dreamy Bee (Alexander) and adolescent Daisy (Kitty Harris), alongside shred-infected brother Gabe (Brent Vermeulen) - by teaching them how to garden (they have to pollinate the plants themselves because the bees are all gone), to read, paint, and pass on the stories of the Before Times.
