Most of the scene of Brandon's resurrection was filmed, however, they did not have any scenes of him actually entering his apartment. So they filmed some shots of only a hand taking down the police tape, and a few shots of the door. Then, using some of the footage from him walking through the alley, they removed Eric ( cookie-cut ) and pasted him into a scene from the doorway of his apartment. They added some rain effects with a computer and viola, he's in his apartment.

You'll also notice that there are few actual facial images of Eric when he's in his apartment. (when he finds Gabriel, the cat, and sees the pictures of him and Shelly) Well, that scene was also created. They used a cut-out of Brandon with the face paint on, and put it on what looks like a cracked mirror, to do the scene where he breaks the mirror. (When you hear The Cure's song Burn) Similarly, when he runs out of the window and swings back in, you can only see his face for a few moments when the lightning flashes. That's a body double, but Brandon's face for those few seconds.

Another added scene, which in my opinion was not done well, but probably as best as they could, is the second roof-top running scene. When he's running from the police, it's a body double. (Just before he jumps down and gets into Officer Albretch's car, which was real.) Somehow, that scene looks quite fake to me. I don't know why. (The first roof-top scene w/ Nine Inch Nails' song Dead Souls was Brandon.)
