Whiplash was nominated as adapted because the director made a short of one scene from the screenplay before making the feature. So it was adapted from it's own script.
A local theater which is currently showing 2 Netflix films but not Glass Onion regularly plays Netflix films a few weeks after appearing on Netflix. I could definitely see them adding Glass Onion for Christmas.
I saw and loved this wonderful movie. Both a good murder/mystery and a good comedy.
Among the many celebrity cameos in this film are two by people who have died in the last calendar year. The movie is dedicated to them.
And yes, the movie ends with the Beatles classic "Glass Onion".
