Ask HN: Geocoding for film/tv/fiction locations, historical events

I am wondering has anyone built a database for the geocodings of historical events. To stretch it a bit more, how about locations that are referred to real world in films, tv or fictions?

I started to think about this problem because I heard a pedicab rider in NYC telling his passengers why this location is famous because it was shown in what tv shows. Then I started to wonder what happened if I can type in a location, then all events happened in past, real or fictional can be drawn up? Or course for historical event, no one will record the locations until the event becomes a past tense. But I think film, tv, fictions may be interesting.
