Here's a video clip showing the session before the recording of a Gundam Double O program (not sure if it's for the special TV program announced yesterday), or a separate interview ("機動戦士ガンダム００総集編 関係者による副音声"?). You can see Director Seiji Mizushima and his team of production staff talking about a lot of things, very casually among themselves. ^^
A very long clip this is.
Video clip is from UStream. Follow this link to the website if you can't see anything.
The director seems to be very busy with his electronic gadgets at the beginning of the clip, XD and other anime series like "K-On!!" and "Haruhi" came up in the conversation as well. There is of course some mentioning of characters from the anime, in Japanese though, which isn't very useful for most of us.
