Dead Set Black Mirror fans, this one is for you. Before Charlie Brooker was tackling the world of dangerous tech, he wrote this horror-drama, which is essentially Big Brother with zombies. It explores what happens when the housemates, who're cut off from the outside world, realise that the world beyond is experiencing a zombie apocalypse. Bonus: it stars a young Riz Ahmed! Watch it on Netflix now. Image Source: Everett Collection
