Christina Ricci (Misty) suggested that her character have a bird because she felt "weird people have birds."
Christina Ricci (Adult Misty) was pregnant during the filming of season 1, and Samantha Hanratty (Teen Misty) was pregnant during the filming of season 3.
The pilot was filmed in November 2019. Due to the COVID-19 pandemic, filming for the rest of season 1 was delayed to 2021, when it was shot from May to October.
The show was originally set in the 1970's flashing forward to the 1990's, but the timeframe was changed to appeal to a wider amount of viewers.
