Several months ago, we learned that Marvel is working on a WandaVision spinoff series titled Agatha: House of Harkness centering on Kathryn Hahn's Agatha Harkness, the breakout character who has been a subject of memes and also nabbed a song that hit number one on iTunes. However, we haven't a lot of updates regarding the project since then and now it looks like we have major news on its alleged release window.
As shared on Reddit by user u/RAMcGonagall, it looks like Agatha: House of Harkness is set to be released on the 2023-2024 TV season. The new information was discovered on the Writer's Guild of America website which revealed that WandaVision writers Peter Cameron, Cameron Squires, and Laura Donney will also work on the series and indicated that the series is being created for the 2023-2024 season meaning that the release window will be on late 2023 or early 2024.
This information has not been confirmed yet by Marvel so we still have to take it with a grain of salt. However, the Writer's Guild of America website is an industry page so it is very likely to be true. There's also the fact that there are reports that the series will reportedly begin production later this year which would be around a year before the alleged release window.
It is great to hear that we now have the potential release window for the series since there are fans who have been looking forward to Agatha Harkness' return to the MCU and seeing her solo adventure which is expected to explore the supernatural side of the franchise even further. While it might be far away, the wait might be worth it and we're going to see a lot of MCU shows between now and then.
According to Marvel.com, the series "will reveal more about the character first introduced in Marvel Studios’ WandaVision. Jac Schaefer, who served as head writer and executive producer on WandaVision, returns for Agatha: House of Harkness. Be sure to hide all dogs named Sparky."
For now, you can revisit the character's journey on WandaVision which is streaming on Disney+.
