You should check out Poker Face by a lot of the same people involved with Glass Onion. Very well written, almost like a modern Murder She Wrote. Also it stars Natasha Lyonne, who I am a fan of because of Russian Doll.
I seriously doubt Netflix will put it in theaters at all, and if they do it will be in a handful to qualify for awards season. When the studios own the streaming channels, there’s very little incentive to release movies in theaters anymore.
