"Mitch isn't trying to recreate something," Howard said. "It's been away for a while, and part of the fun that Mitch has been mining and exploiting is, what's new to discover about these people? What's delightfully unchanged? He and the writing staff and the actors have a fantastic sense of that."

Production on the new season of cult favorite "Arrested Development," which ran on Fox from 2003 to 2006, began last week, with series star Jason Bateman tweeting a photo from the set and writing, "First day. Away we go…"

Netflix gave a 10-episode order to "Arrested Development" and will make all of the new episodes available simultaneously next year.

TV Line first reported Slattery's "Arrested Development" casting.
