Ron Howard Tweets 'Arrested Development' Updates (PHOTOS)

Ron Howard tweets "Arrested Development" photos.

In case you forgot, Ron Howard is here to remind you "Arrested Development" Season 4 is really being filmed. Like, right now. Series executive producer Howard tweeted four new photos from set.

Howard, who will return to the series as narrator, will also appear on-camera in a cameo.

"I'm also told that I’m going to have to make an appearance as I did in the last episode of 'Arrested Development' -- I'm showing up again at some point," Howard told CNN. "So, I'm going to have to film that soon which will be kind of fun. Usually I'm a little too busy, but, with Mitch and 'Arrested Development,' it’s irresistible."

The former "Happy Days" star tweeted a photo with series creator Mitch Hurwitz and star Jason Bateman, the back of Michael Cera's head, an "Arrested Development" logo and Hurwitz behind the scenes working.
