Alfonso Cuarón’s 'Gravity' was a technical blockbuster that reimagined how space could be filmed. Grossing $723 million, the film used a 'Light Box'—a hollow cube lined with 1.9 million LEDs that projected images of Earth and the stars onto the actors' faces. This ensured the lighting on their skin matched the digital background perfectly. The film was famous for its long, unbroken shots (the opening shot is 17 minutes long) and its immersive sound design. It won seven Academy Awards and proved that high-concept 'survival' films could be massive commercial hits if they offered a unique, visceral experience that demanded to be seen on a large screen.
