I meant to post this a bit back, but I think I forgot: Most of the original Matrix movie was filmed in downtown Sydney and it turns out that a few of the scenes were actually shot right outside my hotel. Case in point, a guy on the internet has posted recreation photos of a few scenes in the movie. The one on the right is directly outside my hotel's front door. It's weird that I have walked by that (and a few other places) hundreds of times and never noticed it before.
Downtown Sydney was also the set for Mission Impossible 2 and Superman.
