There’s something really satisfying and simultaneously surreal about seeing the person behind a cartoon voice in the flesh. It’s why Hank Azaria always gets asked to do all of his Simpsons voices whenever he does the late night circuit.

It’s a serious profession undertaken by seriously talented people, but it’s one that’s been shifted to video games as a result of growing popularity and the continued use of movie stars to do animated voices. So it’s a triumph to see a documentary celebrating and exploring that craft.

I Know That Voice features a long list of the best in the business. Billy West, Tom Kenny, Andrea Romano, John Di Maggio, June Foray, Charlie Adler, Carlos Alazraqui and Tara Strong are just a few of the people who lent their voice (and the rest of themselves) to the doc.
