As 'Arrested Development' fans wind toward May and the imminent release of Netflix's revival season, it had seemed the major casting announcements had come and gone, and a trailer would be the next big thing on the horizon. Not so, as we've just learned comic superstars Seth Rogen and Kristen Wiig will appear in the upcoming 'Arrested Development' revival, and you'll never guess as who! Meet the latest additions to the Bluth family inside!

Don't look now, but 'Arrested Development' season 4 has just kicked things up a major notch by adding Judd Apatow favorite Seth Rogen and 'SNL' alum Kristen Wiig. Us Weekly first announced the news of the pair's casting, but Vulture took things a bit further by confirming that Wiig will in fact play a younger version of Lucille Bluth (Jessica Walters) in flashback! For now at least, Rogen's role remains under wraps.

Elsewhere, ‘Arrested Development’ season 4 will feature appearances from Conan O’Brien and Andy Richter, ‘Parks and Recreation‘s’ Ben Schwartz, ‘Up All Night’s’ Chris Diamantopoulos, all three stars of Comedy Central’s ‘Workaholics,’ ‘Mad Men’s’ John Slattery, Isla Fisher and Terry Crews, as well as returning series players James Lipton, Carl Weathers, Jeff Garlin, Liza Minnelli, Judy Greer, Henry Winkler and Scott Baio. Series star Michael Cera (George Michael Bluth) has also officially been added to the writing staff for the effort.
