I have a similar hobby: locating luxury houses that I see in movies, using Google Maps. After identifying buildings in the background, it's a question of looking for the right swimming pool. I've never been to Miami or Los Angeles but I've pinpointed locations in both. Just found a place in Trousdale Estates. It's nice when you find it and verify it's a real place, with the same palm tree and the garden chairs.
The Warriors had a... slightly different scenery. I watched it at the time, on video. The (2006) in the title made me think it was a remake, but it seems to be the date of the article.
