SHH! Don't Tell Anyone: 'Mad Men' Star Joins 'Arrested Development' Revival

"Mad Men" regular John Slattery has joined up with the "Arrested Development" Netflix revival, E! Online (via TVLine.com) spilled Thursday.

Well, here's where a bubble gets burst: we'd love nothing more than to tell you just exactly what machinations will unfold surrounding the dapper Mr. Roger Sterling's appearance. Unfortunately, nobody's being so forthcoming, so that's all there really is to tell right now.

According E!, all that's known is that Slattery won't be a one-off, but playing a character that turns up in multiple episodes of the one-time FOX off-beat comedy's fourth season.

"[Series creator] Mitch [Hurwitz] isn't trying to recreate something," executive producer Ron Howard told MTV.com recently. "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. They're pretty brazen, pretty bold and fearless. That's what made the show into something that fans really kept alive."

He could be The Ghost of Frozen Bananas Past. He could be a silver-fox suitor come to still Lucille Bluth's heart. He could be another attorney come to make Michael Bluth's life a living, hilarious Hell. Possibilities? They are endless.

OK, maybe not "endless." But my imagination is, and that's enough for me, damn your eyes.

Whatever tightly-under-wraps role he's playing, Slattery's turn on the now-in-production series will debut in early 2013 when all 10 fourth-season episodes hit the Netflix streaming library at once.
