WandaVision brought the world of the Marvel Cinematic Universe to the small screen by bringing Scarlet Witch and The Vision to the small town of Westview. From the first episode, things were not normal as the show's entire format shared the look of a classic sitcom.
As the show has progressed, the sitcom stylings have ended as it turned out that Wanda had helped create this entire town and was controlling everything with her immense powers, giving her a "normal" life for the first time, one based on the shows she might have ed watching on television as a child.
The Dick Van Dyke Show
The first episode of WandaVision, titled "Filmed Before a Live Studio Audience," introduced the show's concept. With Dick Van Dyke himself as a consultant on the series, Marvel attempted to make the show as accurate to sitcoms as possible, including understanding what makes them funny, to begin with. When it comes to The Dick Van Dyke Show, the home's entire layout in the first episode is from that classic sitcom, including the area by the front door and the shutters leading into the kitchen.
I Love Lucy
The classic sitcom I Love Lucy also shows up, both in the way the house is decorated and the storyline later in the season. The idea of Vision trying to impress his boss and ending up flabbergasted by his wife, who struggles to maintain the house, is straight out of the Lucille Ball playbook. Also, the bedroom is straight out of I Love Lucy, where Lucy and her husband Ricky Ricardo had two single beds separated, despite being married. That was also the first sitcom to have the beds moved together for a couple. Vision's crazed attitude when Wanda was about to deliver her baby was also out of I Love Lucy.
Bewitched
It is not a surprise that WandaVision would pay tribute to the classic sitcom about a witch, Bewitched. The opening of the second episode, titled "Don't Touch That Dial," had the theme straight out of Bewitched and included several Easter eggs as well. The entire plot of the episode was straight out of Bewitched. Vision and Wanda tried to do a magic show for a charity event, and Wanda continuously using her real magic to make people think it was fake. The only thing she didn't do was twitch her nose.
The Brady Bunch
In the third episode, "Now in Color," WandaVision paid tribute to The Brady Bunch. The television show changed from black and white to color at the end of the second episode, and that led to the color era of televised sitcoms, where The Brady Bunch was always the most memorable.
The house changed its design with the staircase in WandaVision looking just like the one from The Brady Bunch. The addition of the twins, Tommy and Billy, also tied into the idea of having kids, which was a big theme of this newer sitcom.
The Monkees
While it was a small homage, WandaVision also paid homage to a classic sitcom not a lot of people talk about anymore. The Monkees share a lot in common with WandaVision. The Disney+ Marvel show presents itself as a sitcom, even airing on television outside the bubble, but is based on real superheroes. In The Monkees, a real band plays themselves in a sitcom based on their careers as musicians. The end of the third episode has The Monkees' song, "Daydream Believer," play after Monica was thrown back into the real world.
Family Ties
The fourth episode took place mostly in the real world, so there was nothing there concerning the sitcoms. However, the fifth episode was right back to the fantasy world of Westview. This episode had an opening ripped straight out of an '80-era sitcom in Family Ties. This was the show that introduced Michael J. Fox to the world, and the opening had the Keaton family standing still for a painting to be completed of them, which was the exact opening theme for this episode.
Step By Step
The house changed again in the fifth episode. The house's interior looked like it came right out of the sitcom Full House. This makes sense based on the opening. This included the sink where the boys were giving their dog Sparky a bath.
However, the outside of the house had a new design as well. This was more reminiscent of the sitcom Step by Step. This was a sitcom from the '90s that starred Patrick Duffy (Dallas) and Suzanne Somers (Three's Company).
Full House
This is a blink-and-miss-it reference. However, in the opening theme from WandaVision's fifth episode, which was itself based on Family Ties, there were a few other references. The opening pulled the photos of the family growing up from Growing Pains. However, there was also a scene of the family running across a field. This shot came directly from the intro of Full House. What makes this great is that Full House starred Elizabeth Olsen's older sisters, The Olsen Twins, when they were babies.
Malcolm In The Middle
The biggest homage in the sixth episode, "All-New Halloween Spooktacular!" was Malcolm in the Middle. This episode used the same opening of this sitcom, which starred Bryan Cranston and Frankie Muniz. On top of that, the show's look, the characters' actions, and confusion, and the entire idea of the long-lost (dead) brother returning came straight out of that 2000 sitcom. The cast also broke the fourth wall here for the first time, just like Malcolm in the Middle.
The Office
The seventh episode was Agatha Harkness revealing herself that paid tribute to The Munsters.
