CityListBuilder is desktop helper app for iMovie 09 allows to add new cities to the included list of over 4,000 landmarks provided by Apple.
The cities in the list include most large cities and popular tourist destinations. However, if you want to use the new animated travel map feature in your home videos it is likely that you will at some point run in a situation in which your destination is not in the list.
