An instant modern classic.
An indie film crew shoots a low budget, single-take film in a cursed power station and zombies show up.
The camera never cuts! shouts the director.
For anyone with even a passing interest in filmmaking this is an absolute gem, and keeps revealing layer upon layer of itself as the crew dies off and the production threatens to collapse.
A hilarious disaster.
Just make sure you stay all the way through the credits (both times!).
