As of now, there is no confirmed plan for an "Arrested Development" movie. Creator Mitch Hurwitz has expressed interest in a potential film, and there have been discussions among the cast and crew, but no concrete developments have emerged. The show originally aired from 2003 to 2006 and was later revived for two additional seasons on Netflix from 2013 to 2019. Fans remain hopeful, but for the time being, it seems a movie remains uncertain.

Liza Minnelli appeared on "Arrested Development" in Season 3, where she played herself. Her involvement came about through her friendship with the show's co-creator, Mitchell Hurwitz. Hurwitz had previously worked with Minnelli on other projects, and he wrote the role specifically for her. The cameo was also a nod to the show's blend of humor and celebrity appearances, showcasing Minnelli's iconic status in a comedic context. Her character became part of a memorable storyline involving the Bluth family and their misadventures.

Netflix took over "Arrested Development" after the show's original run on Fox ended in 2006 due to low ratings despite a dedicated fanbase. The streaming service recognized the show's cult status and potential appeal to subscribers. In 2013, Netflix revived the series for a fourth season, allowing for creative freedom and a unique release model. This move aligned with Netflix's strategy to invest in original content and attract viewers with beloved shows, ultimately leading to the production of a fifth season in 2018.

In "Arrested Development," Michael Bluth has a romantic relationship with Marta, played by Jessica Walter. Their relationship faces challenges, especially due to Michael's family's interference and the complexities of his life. In the series finale, Michael is set to be with Marta, but she ultimately chooses to pursue a relationship with Gob, Michael's brother. Therefore, Michael does not end up with Marta by the end of the series. Their relationship is left unresolved as the show concludes.
