This documentary is all about the "secret world" of voice actors. And inside scoop if you will. They don't just make voices, they create characters. In some way, they're better than physical actors.

This flick gathers the best of the best in the business. Billy West, Mark Hamill, Seth Green, Phil LaMarr, Nolan North, Hank Azaria, June Foray, Tara Strong, Jim Cummings, Nancy Cartwright, James Arnold Taylor, Daran Norris, Rachel McFarlene, Bob Bergen, these are just a few names from the industry.

This film really does justice to the real heroes behind animation. Watching this will make you appreciate their job more as an art. I watch it every now and then just to remind me how great this is.

Voice acting. I've gotta say,great subject matter for a documentary. It's an unsung talent to a lot of people, and I KNOW THAT VOICE seeks to shed some light on who these well-known voices are. I wholeheartedly confess to the thrill of seeing an actor in an interview launch into the voice of a familiar character, bringing the character to life instantly in that very moment. It's why the Simpsons episode of INSIDE THE ACTOR'S STUDIO was my favorite; seeing the cast do those familiar voices fed right into that delight. And there is a lot of that in this movie, but it's about more than just the voices. It spotlights the legitimate acting and even physicality that go into an actor's time in the sound booth. It's not just a guy doing crazy voices - and seeing these people go from one character to another in a split second is pretty impressive.

The list of people that are featured in the movie is astounding. And it's not just side players and unknowns. We're talking Hank Azaria, Nolan North, Rob Paulsen, Fred Tatasciore, Kevin Conroy, Kevin Michael Richardson . . . these are heavy-hitters with intimidating bodies of work. And let's not forget John DiMaggio (Bender himself!) who directed the whole thing. Says a lot about the man's passion for what he does that he went out and made a movie about these anonymous faces behind the household name voices.

It's a great documentary; breezy, fun and often surprising what these guys can create with their vocal cords. There were still some people that I would've liked to hear from (Frank Welker, Jon Benjamin),but that's hardly a complaint. This is good stuff.

Seeing the face behind the voice of my favourite animated characters is something I've always been curious about. It's great fun to YouTube for voice acting in motion. Watching The Simpsons cast appearance on Inside The Actor's Studio when I was younger was pure magic and I've watched my DVDs of Futurama with the commentaries on several times. Fortunately both shows feature heavily in the documentary with Bender's John DiMaggio being a heavyweight presence here. There's two things that I Know That Voice wants to emphasise. A, it's a craft no less than live action acting. And B, it's way more fun. Gathering a great assortment of voice actors with names you'd recognise from the credits of the cartoons if not the faces, the way the film is brought together gives it a wonderful sense of camaraderie.

However, sometimes it can lead to it feeling like they're simply stroking their own and other's egos but the humility of some of the interviewees shines through. It is disappointing that it lacks an enormous amount of archive footage to show the voices in action. They do it often on camera, sometimes to an irritating extent, and you just wish they would provide examples. Oh well, perhaps the rights would cost an extortionate amount. They do great things with their limited budget here but it does suffer from overeager editing with a pacing that so afraid of us being bored that it instead exhausts our attention. I wouldn't say I learned much about voice actors or gained more respect than I already had, but it was fun and interesting.
