Conan O'Brien, Andy Richter Heading to ARRESTED DEVELOPMENT

TVGuide reports that Conan O'Brien and Andy Richter will guest star on the upcoming fourth season of ARRESTED DEVELOPMENT. Will Arnett revealed the news during his Tuesday night appearance on Conan sharing, "I don't want to give away too much. But let me put it this way. There are a few people on this stage tonight who are a part of it. And I think we know who we are."

No details have been revealed as to the roles the comedians will take on. Richter may return in his role as identical quintuplets (Andy, Donnie, Chareth, Rocky and Emmett) who all have differing personalities.

O'Brien and Richter will join a star-studded slate of celebrities who will appear on the series, airing exclusively on Netflix, including John Slattery, Carl Weathers and Isla Fisher. Arnett confessed that he was thrilled to have so many people, "from strangers on the street to Bruce Springsteen" inquiring about the return of the series. He told Conan, "I'm so excited that people are still into it."

The 13 new episodes are scheduled to premiere on Network in early 2013.
