Let’s set the scene: Duncan Jones, director of the upcoming Netflix thriller Mute, sits down one day with the film’s hairstylist. “So, Mute. It’s a gangster movie set in futuristic Berlin,” he says. “Paul Rudd and Justin Theroux play these two ‘wisecracking American surgeons’ whom Alexander Skarsgård, who of course plays a mute bartender, encounters while searching for his disappeared lover.” The hairstylist abruptly puts up a hand to silence him. “Say no more,” he/she whispers. “Say not one word more. I know exactly what you want.” And it was so.
