And one particular Russian station may have an even more sinister purpose. Featuring computer engineer Andrus Aaslaid, historian Maris Goldmanis, and documentary photographer Lewis Bush.

The Art of Foley: Bringing Slimer & Batman to life
When it comes to film sound, "Foley Artist" might be the most important job you've never heard of. These performers record custom, synchronized sound effects to create the sounds for characters' footsteps, movements, and much more. It's exhausting and delicate work, and when it's done right, the audience doesn't even notice it's there. In this episode, we tour the Warner Brothers Foley stage with Foley Artists Alyson Moore and Chris Moriana, and Foley Mixer Darrin Mann.
