This is the trailer for I Know That Voice, an upcoming documentary about voice actors. The trailer unfortunately makes the film look unfocused and lacking a point of view. The primary appeal of the documentary (if the trailer is any indication) appears to be filmed interviews with lots of popular voice actors talking about themselves and being goofy onscreen. Four minutes of that goes a long way. Let’s hope the final product offers some greater insight into the art of voice acting besides revealing that Mel Blanc was a legend and actors do video game voice-over nowadays.
