21 “Agatha All Along” Behind-The-Scenes Facts That Only True Fans Know

There are MASSIVE spoilers ahead for Agatha All Along!

1. One of the reasons Agatha All Along came to fruition was that showrunner Jac Schaeffer (who was also the head writer and executive producer of WandaVision) involved the character Agatha in some form or fashion in every new idea she developed and pitched for Marvel after WandaVision finished.

2. There was also a “creative” reason why the title of the show kept changing earlier in the year before it finally became Agatha All Along.

3. When Kathryn Hahn found out that she was going to get her own show as Agatha, she only told one person the truth.

4. Joe Locke’s audition process for Billy/Teen took six months to complete.

5. Sasheer Zamata (who played Jen Kale) loved WandaVision and was asked to audition after filming her stand-up special, for which she researched witches. When she got cast, she emailed the producers afterward, saying, “Did you know that you hired a witch? Could you tell?”

6. Joe Locke worked closely with Jennifer White, who was also Elizabeth Olsen and Kathryn’s movement coach in WandaVision. They worked together to find similarities in the way Wanda and Billy used their magic. “Fans of the comic corner know that Billy’s powers are pretty much the same as Wanda’s with a few differences, so we wanted to find similarities with that, but also his own finesse,” he told Entertainment Weekly.

7. Every single effect on set was “almost wholly practical” in the show, from the Witches’ Road to the monsters each of the actors interacted with to natural elements like a practical mud pit and fireflies. “We really wanted to be authentic to old Hollywood filmmaking techniques,” executive producer Mary Livanos told IGN, with Jac crediting Mary for the original idea. “WandaVision was a celebration of the golden age of television and the celebration of sitcoms,” Livanos told Variety. “[In Agatha All Along,] we’re really honoring the craft of filmmaking and the golden age of fantasy and horror.”

8. Yes, even the swords in Episode 7, “Death’s Hand in Mine,” were practical. According to Jac, they were sharp, made of real metal, and positioned with piano wire to map out each sword’s “fall.”

9. Talking about Episode 7, Jac also said the way the swords drop is supposed to mirror how Lilia views and is “wrenched” through time.

10. As for the writing of Episode 7, Jac said they wrote the episode first and then sprinkled in the “flashbacks” into the earlier episodes to make it all connect.

12. So it may make sense why Agatha All Along is officially the “least expensive show” Marvel Studios has made to date.

14. Agatha’s signature makeup style was inspired by ancient Greek pottery and the rock ‘n’ roll band Siouxsie and the Banshees. According to makeup department head Vasilios Tanis, he also thought of dipping Agatha’s fingers in black paint in WandaVision.

15. Agatha’s hair is also symbolic of her mental state throughout Agatha All Along. For instance, in the beginning episodes, she ties her hair into a tall, Gibson Girl–inspired updo to visually convey that she’s in control. However, her hair gets looser the further they travel on the Witches’ Road.

16. As for the rest of the cast, each of their costumes evolved after each trial. Costume designer Daniel Selon said he put Easter eggs in each of their costumes on purpose. “I approach that by planting seeds on the initial costume that you see them in. And by seeds, I mean Easter eggs and sort of the silhouette is established there, and within the framework of that silhouette, we slowly change things like Billy’s blue hoodie slowly turns red once he bleeds into it in episode four. And so you know that is slowly revealing his shift into who he becomes,” he told Variety.

17. Rio’s costumes (played by Aubrey Plaza) visually went from “life” to “death” throughout the show.

18. For Episode 7, each “film witch” was tied to a character for very specific narrative reasons.

19. The scene in Episode 5 where Agatha is interrogating Billy in her home was mostly improvised by Kathryn.

21. And finally, while almost all Marvel TV shows and movies have post-credit scenes, Agatha All Along does not. The reason? Marvel decided to forgo one for a reason that wasn’t provided.
