"Mad Men" star Slattery, who plays senior partner Roger Sterling on the AMC drama, will appear in multiple episodes of the Netflix-revived "Arrested Development," an individual close to the production told TheWrap.
Details on Slattery's character, or how many episodes he will appear in, were not available.
Series producer and narrator Ron Howard told MTV News on Wednesday that series creator Mitch Hurwitz would be introducing new characters to the resurrected show.
"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.
