This is a sample of one of the 170ish vfx shots in the film. This was a pickup, shot against green screen after main unit completed (it was shot in a living room believe it or not). From that point on, pretty much everything is vfx - from the background, the weather, the glass, rain and atmosphere.
The video shows some of the layers involved in building up the scene, it loops as the layers are built up. The final shot in the film is actually in black & white, but even so the vfx work was carried out in colour. The scene was composited Nuke X from the Foundry.
