Everyone loves Muppets. Knives Out Glass Onion is just brilliant. Why not mix the two? Many others have thought of this idea and it’s definitely a very entertaining thought experiment. Rian Johnson has even said that he’s considered it but eventually decided against it. I think his motivation is solid. Nerdist has made a brief video titled Rainbow Connection – A Benoit Blanc Mystery. This takes footage from both Knives Out movies and different Muppet movies to create a trailer for a mashup movie.
