This might shock you, but many movies are not filmed on location. Yeah. Sometimes they're filmed in completely different countries. Sorry, but it's time you knew. This map from Paramount Studios, produced in 1927, showed investors where movies could shoot, instead of going to the actual places. Does your movie take place in Venice, Italy? No problem, head down to southern California. How about the Mississippi River? Check out the Sacramento River.
