Earlier this year during the Oscars, Chris Rock called voice acting one of the easiest jobs in the world. Well, it seems one documentary is ready to prove him wrong. I Know That Voice takes some of the most popular voiceover artists in the business, and gets them to explain the in and outs of the job. With a very extensive cast list, the somewhat lengthy trailer only gives you an interesting peek at the men and women behind the cartoons.

Tara Strong, Rob Paulsen, Tom Kenny, John DiMaggio, June Foray, Jess Harnell, Billy West, Kevin Conroy, and more? It really seems like they’ve rounded up quite the amazing bunch of people to discuss the topic.

We get a glimpse at some of the characters they voice, especially Strong’s characters as well. I think hearing their opinions on video game voice acting is certainly going to be interesting, especially as there hasn’t been much of a peek behind the curtain of the craft as opposed to television voice acting.

The film currently has no release date, but look out for it sometime later this year.
