Isla announced on her Instagram page a few days ago that she is “back on Arrested Development” – she will re-join the show for their 5th season, after her guest stint on season 4 back in 2013. Season 5 started development last month, and is set to air on Netflix in 2018.
Star Jason Bateman teased the premise of the 5th season to Entertainment Weekly a few months ago, saying:
Season 5 of the quirky comedy will involve a murder mystery, Bateman teased earlier this month on EW Radio (SiriusXM, channel 105), picking up with the events of season 4, which debuted on the streaming service in May 2013.
“The central spine of that story of is the death of Liza Minnelli’s character [Lucille], and a bit of whodunit, who may have done it, who had something to do with it,” Bateman explained. “That’s sort of a central thread around which [creator Mitch Hurwitz] is going to braid in all the colorful plot complications that he knows how to do.”
Unlike season 4, when episodes focused on individual characters rather than group scenes — a workaround due to cast scheduling conflicts and commitments — Bateman, who popped up in various scenes to help anchor the show, says the cast will be together for the new 15-episode season, which will debut in 2018.
