Roddy McDowall was the man...uh...ape.

One of these days, I want to visit Century City, (where Conquest was shot) and see if I can spot the actual locations used. Some of it must look the same four decades later?

I was there a few years ago doing that very thing. The most recognizable areas I found from "Conquest" are on the outskirts and inside of the outdoor shopping mall and the grounds around the adjacent office buildings located at the corner of Avenue of the Stars and Santa Monica Blvd. There is the pedestrian foot bridge and plaza from the ape riot scenes that spans Avenue of the Stars. It's still there, the bridge where the Ape Control riot police have a stand off with a huge mob of Apes. You do get that instant recognition when you go to certain areas, and see the exact same office buildings that burn at the end of the film. Some of the same lamp posts and path stone work had been there from the early 70's. You better hurry, they have been doing updating and renovations on the other side of the mall area recently.
