Episodes end with scenes appearing "on the next Arrested Development". Most of the time, these scenes don't appear in the next episode, but are part of the series' continuity.
SPOILER: The mysterious cooler containing incriminating evidence against the George Bluth Sr. featured in the episode "1-18 Missing Kitty" (among other episodes) has the name "H. Maddas" written across the side. "H. Maddas" written backwards is "Saddam H."
In one episode, Henry Winkler looks in a mirror, starts to comb his hair, then puts his arms out, just like Fonzie in the opening credits of Happy Days.
Lucille Austero's nickname is "Lucille 2".
The nickname "Gob" is based on his initials (George Oscar Bluth).
Before each commercial break, the scene cuts to an all-white screen instead of a typical all-black screen.
Neither David Cross's nor Jeffrey Tambor's characters were ever intended to be regular characters. It wasn't until the actors tested so well that the writers ended up putting them regularly in the series.
The song that plays whenever GOB performs on stage is "The Final Countdown" by Europe.
Even before the "Altar Egos" episode, posters reading Save Surely can be seen on the walls when George Michael and Maeby are at school.
The show is shot as a documentary, so character's swearing is bleeped out. However, the producers must find ways to obscure the mouths of the characters who are swearing so that their mouths don't have to be blurred out. This is often accomplished by cutting to a shot of another character reacting to the swearing, or by blocking the mouths with objects. Sometimes the characters resort to just covering their mouths with their hands.
Martin Short's character Uncle Jack is based loosely on real-life 90-year-old fitness guru Jack LaLanne. Speech mannerisms, style of dress, and even the dyed jet-black hair are all trademarks of LaLanne, who, unlike Short's character, was extremely mobile and agile at the time the episode aired.
In the pilot both the model house and Lucille's houses were completely different. Tobias also had different glasses, Buster had longer hair and George-Michael had darker skin.
In the second season, the Bluth Company housing order is cut back from 22 to 18. This is a reference to FOX cutting back the order of episodes of the second season from the usual 22 to 18.In the third season, FOX cut the third season's episode order from 22 episodes to 13 episodes.
Most of the websites mentioned throughout the series (such as www.imoscar.com, www.never-nude.com and www.barrygood.biz) did exist and could be accessed by the public while the show was on the air. Since then nearlly all the domains have expired; the ones that still work will forward you to the Fox website instead.
Tobias' "nevernude" condition is a real psychological affliction known as gymnophobia, the fear of nude bodies.
Recurring character Starla had always claimed she had a relationship with Quincy Jones. The actress who played Starla, Mo Collins, is a former cast member on the Fox sketch show MADtv which Quincy Jones produces.
'Ron Howard''s role as the narrator was accidental. He was merely filling in on the pilot and his voice just "worked".
In the Season 1 finale "Let Em Eat Cake", Alessandra Torresani played George Michael's girlfriend Ann, and her brief performance was singled out for praise by the rest of the cast on the DVD commentary for the episode. By Season 2, however, Ann was played by the very different-looking Mae Whitman. This casting change is possibly a joke, since Michael repeatedly forgets what Ann looks like, and Maeby jealously calls her "No Face".
In the pilot, Michael is seen applying for and receiving a position at what the narrator refers to as a "rival firm." The sign behind the employers reads "Sitwell."
When a photo is shown of Rita (Charlize Theron) from before her plastic surgery, it is actually a film still from _Monster_(2003)_, for which Theron famously gained 30 pounds and underwent extensive special effects makeup regimens to make her look rougher and less advantaged.
David Cross was originally approached to play Buster Bluth, but chose to play Tobias Funke.
The branch insignia disc on Buster's Army dress uniform indicated he was part of the Air Defense Artillery branch, meaning his specialty was probably as a Patriot Missile Battery operator or an Avenger Air Defense System crewmember.
SPOILER: After Buster discovers that his biological father is not George but George's brother Oscar, he regularly calls Oscar his "uncle-father." This is a reference to Hamlet, Act II, Scene 2: "... my uncle-father and aunt-mother are deceived... I am but mad north-north-west: when the wind is southerly I know a hawk from a handsaw."
