My friend and I were psyched to go to the play King Charles III on Broadway in 2016. We had read the rave reviews and heard the buzz. Come intermission, we looked at each other and said, pretty much at the same time, "What's the big deal?" and "It's good, but..." When the second act ended, we looked at each other and said, pretty much at the same time, "Now I understand," and "Wow!"
I didn't rush to see the movie version, which came out in 2017, because I didn't want to mess with my memories of the play, which was so damn good. But, more recently, I decided to watch it because
(1) Enough time had passed;
(2) The screenplay is by the playwright, Mike Bartlett; the movie is directed by Rupert Goold, who also directed the play; and most of the original Broadway performers are in the movie; and
(3) For some strange reason, King Charles III has been on my mind recently.
The movie is remarkable, every bit as good as the play, so much so that I'm linking to my original review, here. I would only add that Bartlett was so insightful as to be prescient. (If you watch the movie, and you should, keep in mind that the play first appeared in 2014.) I'll be fascinated to see how much life imitates art going forward.
