Start by identifying what was filmed on location and what was created on a set or with visual effects. Fan pages can provide leads, but confirm real places with reliable, current sources before building a route.
Check whether each location is public, private, residential, ticketed, or sensitive. Follow signs, avoid blocking homes and businesses, ask before photographing people, and never enter restricted property for a scene match.
Plan for the destination beyond the screen. Group verified locations into a sensible route, add local businesses or cultural sites, and keep an alternative for closures, crowds, weather, or a place that looks very different today.
