While developing the role of Kase, creators Matt Hubbard and Alan Yang referred to her as a "Catherine Keener" type. Luckily, they were able to find the perfect match with the actress herself when she accepted the role.
Production designer Amy Williams, used bushes and trees to cover the mailboxes in the Riverside Former community. All cars were removed from the street, and all electronics were removed from the interiors to add to the feeling of isolation and timelessness.
Kase's house is a redressed version of Oscar and June's house set. To match the geography of the exteriors, the scenes were shot and then the image was flipped in post.
Maya Rudolph had some experience making pottery herself, but a consultant was brought in to make the more complicated pieces.
Multiple versions of the cupboard in Kase's home were created to be lit on fire. The one that June and Kase carry to the backyard was made of foam.
