Fox Studios:Stage 15 (the party scene on the 30th floor was filmed on the soundstage as the set as designed was too large to construct inside the tower)
Fox Studios:The newly-completed Fox Plaza building (which overlooks the studio lot) featured in exterior shots as Nakatomi Plaza. Scenes of destruction were accomplished using scale models. Many sequences were actually filmed on the vacant (and still under-construction) 33rd & 34th floors, with additional breakaway walls for stunt purposes.
