Conan O'Brien and his trusty sidekick join the ever-growing cast of the revived cult favorite "Arrested Development"
"Arrested Development" is adding a splash of Coco to the mix for its upcoming fourth season.
Talk-show host Conan O'Brien and his faithful sidekick Andy Richter will appear on the revived cult favorite, which will premiere on Netflix in spring 2013.
"Arrested Development" star Will Arnett — who plays Gob Bluth on the show, which ran for three seasons on Fox from 2003 from 2006 — made the reveal while appearing on O'Brien's TBS show Tuesday night.
“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 [the upcoming season],” Arnett told the pair. “And I think we know who we are.”
Richter has previously appeared on "Arrested Development," guest-starring in Season 3 as himself and his four identical siblings, a riff on Richter's former Fox sitcom, "Quintuplets."
The upcoming fourth season of "Arrested Development" — which was originally slated for 10 episodes but will likely receive more — has drawn a cavalcade of new and returning guest stars, including Henry Winkler, Liza Minnelli, "Mad Men" star John Slattery and "Three Stooges" actor Chris Diamantopoulos.
