Eastwood had clear childhood memories of 1930s Los Angeles and attempted to recreate several details in the film: the town hall, at the time one of the tallest buildings in the city; the city center, which was one of the busiest in the world; and the "perfectly functioning" Pacific Electric Railway, the distinctive red streetcars of which feature closely in two scenes. The production used two functioning replica streetcars for these shots, with visual effects employed for streetcars in the background.
