I loved the movie "Sunshine", but I thought they missed a golden opportunity with physics and gravity. In the film, they ship is transporting a bomb roughly the size of Manhattan. The bomb is at the front of the ship, with a long crew compartment behind it, kind of like a bus. The bomb itself was large enough to have it's own gravity. In the film, the crew compartment's gravity is what you would think of on a bus- you can walk the length of it with the gravity being on the "floor".
With just some changes to set design, they should have had the center of gravity been the bomb, so that the crew compartment needed to be climbed up and down, like a bus on it's side.
