It almost sounds like a challenge: Can you make a feature length movie with only one on-screen actor, one location, and a budget of less than half a million?

Written by Lucy Campbell and shot by Matt Vesely, eerie sci-fi mystery Monolith exists within these potentially tricky parameters. Almost the entire movie takes place in a modern, isolated house in the rolling Adelaide Hills, South Australia, following a disgraced journalist (Lily Sullivan) as she yarn-balls a weird global enigma for her new podcast series. The film could easily have been a dismally failed experiment, but Monolith's logistical restrictions actually help it shine, adding a claustrophobia and sense of realism that only heightens the core mystery.
