2. The Run Time Is Exactly The Same As The Debris' Orbit
There's always the question whether a filmmaker intended much of the depth their movies are allotted. Room 237 set out to show the genius of Stanley Kubrick's obsessive eye but with its crazy, unproven theories instead had everyone questioning just how much of these readings was actually intended. With film theory, as with any art, there's always going to be a line where you have to question whether you're over-thinking it. The pinnacle of this is when the running time matches perfectly with an element in the film. Inception runs at 2 hours 28 minutes while its central song Non Je Ne Regretten Rein is 2 minutes 28 seconds, evoking the time slow down between levels. Now Gravity's may be less provable than that, but it's still pretty cool. Despite the many lengthy shots leading into each other, Gravity doesn't run in real time. Instead, it runs at 91 minutes, damn near identical to the time it takes for the satellites to go round the Earth once. Given initial rumours that the film had a much longer running time, it seems it may just have been intentional.
