Rogen's part has not been revealed. However, Vulture is reporting that Wiig, late of "Saturday Night Live," will play a young Lucille Bluth (Jessica Walter) in flashback. And since Rogen's involvement was announced simultaneously, it probably wouldn't be a wild guess to peg him as a young George Sr. (Jeffrey Tambor).

After Liza Minelli -- who revives her semi-regular role as Buster's (Tony Hale) girlfriend, Lucille 2 -- Wiig and Rogen are now the show's biggest guest stars on a list that also includes Conan O'Brien, Andy Richter, John Slattery, Terry Crews and Isla Fisher.

Season 4, currently shooting, will consist of 14 episodes -- each focusing on a core cast member.

"Arrested Development" will premiere all its Season 4 episodes on a single day this spring on Netflix.
