If you haven’t seen Gravity yet, you are missing out on something pretty amazing. The special effects have a realism to them that takes Gravity to a new level for space movies. Now, we’ve got this great new featurette from the film on just how they made it happen.

Official Synopsis:
Sandra Bullock plays Dr. Ryan Stone, a brilliant medical engineer on her first shuttle mission, with veteran astronaut Matt Kowalsky (George Clooney) in command of his last flight before retiring. But on a seemingly routine spacewalk, disaster strikes. The shuttle is destroyed, leaving Stone and Kowalsky completely alone–tethered to nothing but each other and spiraling out into the blackness. The deafening silence tells them they have lost any link to Earth…and any chance for rescue. As fear turns to panic, every gulp of air eats away at what little oxygen is left. But the only way home may be to go further out into the terrifying expanse of space.
