What interests me is that there's some production specifics. The next film, Knives Out II, will begin production incredibly soon--on June 28th in Greece. And that as it stands, casting is now officially underway. I get the sense that for the sake of these sequels, we'll see a more global side for LeBlanc as a detective; and it would make sense considering the 200M for each film. Additionally, if each film will differ, that means Rian should already have the core plot for both Knives Out II and III ready, meaning this might be a quick turnaround (that way, to allow him to get to work on his Star Wars project too).
It certainly is a highly fascinating choice. And I wonder how soon we'll hear on casting for the ensemble of Knives Out II.
