Persnickety birders — as if there is any other kind — once made a fuss when a network added bird noises to a golf broadcast that turned out to be recordings of a non-native species. An effort at providing a hyper-realistic viewing experience was foiled by being wildly inauthentic (and by the network not realizing there’s a large crossover between birders and golf fans). It’s no surprise, though, that Lincoln, a film so dedicated to authenticity that Daniel Day-Lewis did everything to become Honest Abe short of gene-splicing, paid extra attention to the realness of its sound. To that end, the Tennessee State Museum is hosting a discussion titled “Hollywood and History: Capturing Accuracy in Spielberg’s Lincoln.” A key member of the film’s sound department will discuss the lengths Steven Spielberg went through to ensure that even the sound was on-point — the ticking of Lincoln’s actual watch, the creaking of a church pew he actually sat in and the like. The presentation will be followed by tours of the National Archives’ excellent Discovering the Civil War exhibit.
