Having read the book, Midnight In the Garden of Good and Evil, a true account of a Savannah, Georgia murder in 1981, I became familiar with the existence of Mercer House in Savannah. I did not view the film by the same name, however. The mansion's beautiful Italianate construction was begun in 1860, but finished after the war. It was built by the great grandfather of Johnny Mercer, the composer. It's history is easily located on the web. Ironically, it was used again in the movie, Glory, about the first all-black Union infantry regiment and their bravery while being led by a northern-bred abolitionist colonel. For a movie showcasing Union troops, I find it interesting that a southern mansion was used as a backdrop to highlight a northern aspect of the War. At the end of Midnight... the author tells of Mercer House being used by a movie company for Glory and how the street/square was overlaid with dirt depicting an 1860's street. I assume some of that was cut because the dirt street doesn't appear in the film. I also find it amazing that so much of Savannah was spared destruction by northern troops. Thank goodness!
