"Arrested Development" had its final broadcast on February 10, 2006 and concerned Michael Bluth (Jason Bateman) and his eccentric family comprised of his son George Michael (Michael Cera), his father George Bluth Sr. (Jeffrey Tambor), his mother Lucille (Jessica Walter), his brothers George Oscar Bluth II (Will Arnett), Buster Bluth (Tony Hale) and sister Lindsay Funke (Portia de Rossi), and Lindsay's husband Tobias (David Cross) and their daughter Maeby (Alia Shawkat).
Michael is the most level-headed and knowledgeable about the family company and it makes perfect sense that he should be handed the position, but George Bluth Sr. gives the spot to Lucille instead and at the worst possible time.
They said they reveled at the chance to jump back into the shoes of their Bluth personae, and Jessica Walter had no trouble slipping into boozy matriarch Lucille.
