An app that uses Google maps and displays the locations, where movie scenes were shot. The idea was inspired by the idea "Feature showing filming locations of TV shows and movies".
Locations, where movie scenes were shot, are usually disclosed to the media after the movie/ series is released. People, upon learning about the place, want to visit such locations. Although it is not feasible to visit a place just for the film location, it would be great if someone could prompt you that a famous scene location is just a km away from you. This is what the app will do.
Users visit famous locations and click and upload photos to the app just like they do on any social media site. Either you upload the location along with the photo, or if you want to edit the photo and then upload it, you add the location later on. You link it to the scene from the movie or series. If possible, you mention the Youtube link of the scene or the time (along with the season and episode for series) when the scene appears. This then enters the database of the app. Others learn about the location if they are in the vicinity (you can set the vicinity range in km).
Also, if you are planning to visit a certain city, you can view the famous locations beforehand using the app. You could sort the locations that have had more than a threshold visitors, so you know that the place is really famous. You could also select a city and then select the movie or TV show you like. It will give you relevant hits. You could also select the city and the actors to get relevant hits. You would then learn of the location where Audrey Hepburn ate ice cream in the movie "Roman Holiday". The location is Spanish Steps in Rome.
It need not be a separate app and could be an add-on feature to either Google maps or other social media apps.
