The Bluth Family is finally coming back with new episodes of Arrested Development set to debut on Netflix next year. Last night, series star Will Arnett appeared on the TBS late-night talk show Conan, where he revealed that Conan O'Brien and Andy Richter will appear in Season 4. Take a look at the video, then read on for more information about the series.

As you can see in the video, it isn't known who exactly Conan O'Brien and Andy Richter are playing, or if they will appear as themselves. Andy Richter guest starred as Chareth Richter (and several other Richters) on a 2006 episode of the series. They will join new cast members John Slattery, Isla Fisher, and Terry Crews, along with returning favorites such as Henry Winkler as Barry Zuckerhorn, Liza Minnelli as Lucille Austero, and Carl Weathers as himself.
