If you need any other proof that the filmmakers behind Lincoln went above and beyond the call of duty to make the film as authentic as possible, sound designer Ben Burtt tracked down one of Lincoln's original pocket watches and recorded its actual ticking sound. That's dedication.
The film's sound team also visited the White House with their gear so they could record the creaking of the mahogany doors that existed when Lincoln was president, as well as the chimes and movements of the various clocks that now reside in the Lincoln bedroom. So not only does Daniel Day Lewis's performance help take you back to the time of the Civil War, almost everything you hear in the theater will as well. [Vimeo via The Verge via Open Culture]
