20 Things You Didn't Know About Interstellar

20. Some Individual Frames Took 100 Hours To Render

Nolan and his team of filmmakers and experts (including renowned theoretical physicist Kip Thorne) wanted Interstellar to be as scientifically-accurate as possible, especially when it came to depicting wormholes and black holes.

And - to simplify things greatly - this meant that the movie's special effects were pretty darn complicated to produce.

But how complicated exactly? Well, visual effects house Double Negative had to develop new rendering software based on Thorne's equations, and overall, it took a ridiculous amount of time to develop the movie's 850 effects-laden shots.

In fact, some individual frames took a staggering 100 hours to render, with the film clocking in at 800 terabytes of data by the time it was completed.

Movies commonly run at 24 frames-per-second, so, potentially, Interstellar could've required 2,400 hours to render one second of footage. Mad.
