’Arrested Development’s’ development is not arrested. Last night, Jason Bateman tweeted this picture along with the message: “Taken at AD mission control, today! All systems are go. Filming for the new episodes starts in four weeks. Woo!†Woo, indeed. Ron Howard added a much more adorable version of the same picture and a photo of the color index card filled writers’ room. (Both of which are below.) No word yet if the writers were replaced by colorful index cards or if they’re just being used to keep all the callbacks and callfowards straight. We’re onboard, either way.
