TV Guide reports that a new documentary about voice-over artists, titled I Know That Voice, has hit VOD platforms and iTunes this week. Producer and Annie Award winning actor John DiMaggio says he signed on to the film because “I want my peers to get a little bit of recognition. These are some of the most talented people I know, and some of the most brilliant character actors that I know.” While the film conveys how much fun the job is it also “emphasizes that these vocal gymnasts are, first and foremost, actors. A good Christopher Walken impersonation will only get you so far in the business, while the most successful voice actors have mastered the ability to convey every possible emotion without the benefit of facial cues”.
