[IMDB] [Google Map] This Speed (1994) filming location looks almost unchanged. I grabbed brunch there and the interior is different from the movie.
[IMDB] [Google Map] The photos below show the building used for the interior scenes in Saw (2004). I didn't go inside but there's a video below with a (then versus now) look at the interior (and more).
[IMDB] [Google Map] This location is from the "Fire Alarm" scene where they showed multiple photos in black and white style and a quick slide show. The video above talks about this scene at ~27 minutes.
Thanks for reading, JS.
