Who hasn’t done a quick search on Wikipedia to reference a word, a person, a country, or anything, actually?!
For fun, I plugged-in "Voice-Actor" and beyond a lengthy article expounding on the profession, I ended up following a link to a supposed Documentary DVD entitled: "Adventures in Voice-Acting".
The article goes on to say it is: "…produced by Bang Zoom! Entertainment containing interviews with close to 100 voice actors, producers, and casting directors that are in anime dubs and video games. The DVD was reported to be released in 2007, but it’s current status is unknown…"
Anybody heard of this? The article — found here — also lists all the voice-actors who contributed to this DVD.
