There are many things that go into the making of film that we, as viewers, never think about. Some of these require a great deal of thought and art to accomplish. Here is an interview with Gary Rydstrom, the sound re-recording mixer for Steven Spielberg’s Lincoln. Mr Rydstrom has worked on many movies with Spielberg since 1989 and has won seven Oscars. Among other things, he speaks about the presence of ticking clocks in Lincoln’s time and the use of the clock as metaphor, as well as the use of Lincoln’s actual pocket watch in the film.
