Most recently, co-creator of the FX series Fargo Noah Hawley attempted to adapt Cat's Cradle as a limited series. Leonardo DiCaprio's production company attempted to adapt the book into a movie back in 2005, but the film never moved past the writing stages. Elements of the novel were adapted for the 1972 TV movie Between Time and Timbuktu, a project that pulled from several different Kurt Vonnegut stories. There have been multiple attempts to bring Cat's Cradle to both the big and small screens. I don't really know how you would get audiences on board with watching an adaptation of a novel that works so well because of how fast-paced it is, or how singular the author's sense of humor is. For instance, boku-maru is an act of worship in Bokononism when two people press the exposed soles of their feet together for a long period of time. This is mostly explored through a fictional religion, Bokononism, a pretty hilarious concept that is participated in through extremely odd practices. (Either that or how they willingly turn a blind eye.) Other times, Vonnegut jokes around in the parameters of philosophy and religion.

This is done so in a way that comments on how unaware people can be of what their government is up to.

It's just, you know, a Kurt Vonnegut novel! He makes light of things that are touchy subjects, like discussing what North American civilians were doing the day the atomic bomb was dropped on Hiroshima. Not that the book is offensive or 'couldn't be made today' because of jokes that just didn't age well. The novel's sense of humor also just likely wouldn't translate well onto the screen.
