Movie trailers have undergone a huge evolution. They’ve gone from those cheesy voice-of-God narrators in the ‘80s and ‘90s, to boojes and bwaas. Professor James Deaville delivers the history of trailers, and Youtuber Craven Moorhaus offers a hilarious takedown of the sounds and dialogue that are common in the modern trailer style. After you hear this episode, you’ll never be able to watch a blockbuster trailer the same way again. Twenty Thousand Hertz is produced out of the studios of Defacto Sound and hosted by Dallas Taylor. Follow the show on Twitter & Facebook.
