Locations
This movie's imdb page has no section for locations. Any Los Angeles residents know the apartment building where Janet Leigh gets shanghaied by Warren Stevens and his henchmen?
I figured out that
(1) the confluence of freeways surrounding the Hotel containing Janet Leigh's apartment/hideaway (i.e., the background during the rooftop scenes) is the middle of where the 10, 5, 101, 60 converge in the Boyle Heights area of Los Angeles:
1109 S Boyle Ave (approximately)
Los Angeles CA 90023

(2) The address of the "Kelly Building" containing Parker's 30th-floor apartment is
AT&T Center (formerly the TransAmerica Building)
1150 S Olive St
Los Angeles CA 90015
