Ever Wondered How Filmmakers Defy Gravity on Film?

Ron Howard chose to shoot in real weightlessness for his 1995 film Apollo 13, a dramatisation of the near-disastrous moon mission that saw astronauts Jim Lovell, Jack Swigert and Fred Haise temporarily stranded in space after an explosion in an oxygen tank. Howard and his team – including actors Tom Hanks, Kevin Bacon and Bill Paxton – took numerous flights in the KC-135 “vomit comet”. This NASA training plane flies in a steep parabola so that passengers can experience 25 seconds of weightlessness on the way down. 

612 parabolas were required for Howard to capture the pieces of the action he needed. Apparently few people lost their lunch, though minor bumps and bruises were sometimes sustained when weightlessness ended. “It was difficult to do,” said the director at the time, “but it was an extraordinary experience.” The vomit comet footage was intercut with lower-tech angles where the actors were simply standing on see-saw-like boards which grips could gently rock up and down.

For a 2006 episode of Doctor Who, “The Impossible Planet”, the production team used Pinewood Studios’ underwater stage for a brief zero-gravity sequence. MyAnna Buring’s character Scooti has been sucked out of an airlock by a possessed colleague, and the Doctor and co watch helplessly through a window as her body floats towards a black hole. Buring was filmed floating underwater, which enabled her long hair to flow out realistically, and then composited into CGI of the black hole by The Mill.

On the whole though, wire work is the standard way of portraying zero gravity, and a particularly impressive example appeared in 2010’s Inception. Director Christopher Nolan was inspired by 2001’s weightless scenes, for which Kubrick often pointed the camera straight upwards so that the suspending wires were blocked from view by the actor’s own body.

Inception sees a fight in a dreamscape – represented by a hotel corridor – becoming weightless when the dreamers go into free-fall in the real world. The scene was shot with a 100 ft corridor set suspended on end, with the camera at the bottom shooting upwards and the cast hung on wires inside. (Miniature explosions of spacecraft traditionally used a similar technique – shooting upwards and allowing the debris to fall towards the camera in slow motion.)

2013’s Gravity filmed George Clooney and Sandra Bullock in harnesses attached to motion-control rigs. Footage of their heads was then composited onto digital body doubles which could perfectly obey the laws of zero-gravity physics.
