Was the movie Gravity filmed in space?

This 3D movie contains a lot of long shots and smooth camera movements, which makes the beautiful and dangerous space environment more realistic and richer in details. This is the level reached by director Alfonso Cuarón, photographer emmanuel lubezki, visual effects director Tim Webber and their team after five years of cooperation. Lubezki claims that in the gravitational outer space scene, only the face of the actor under the helmet is actually photographed, which makes the film more memorable technically and aesthetically. Everything else in the outer space scene, including the spacesuit, the space station and the earth, is made by CG. Similarly, in one scene, Si Tong floats on a spaceship without a spacesuit. Brock is hung on the set by a steel wire, and her surroundings are digitally made.
