Here something really cool from the foreign exchange company Travelex. It's an interactive world map that's focused on the IMDb top 250. Using the map, you can pinpoint all of the filming locations for each of the films.
If you filter for The Empire Strikes Back, for example, the map points out Hardangerjøkulen Glacier in Norway, Lee International Studios in the UK, and Alcatraz Island out in San Francisco. Technically Alcatraz was just used for a sound effect: Darth Vader's shuttle door was the sound of every door on a cell block slamming shut.
(Note: No locations are given for animated films. Hearts aren't on maps, kiddo.)
Check out the Movie Lover's Guide to the World after the cut.
