Here are the shots I had time to do.
My camera lens is way different but I tried to match the angle up as best I could.
Some of the hallways were covered to make them look like walls, and the wall where the sliding door opens is fake. You can see the stairwell in the background.
Also, the windows behind the desk are fake. It's a fake wall also. They must have backlit photos to make the scenery outside the window. It looks like the transco tower outside the middle window.
