That looks pretty good, like a real big screen movie. My only complaint is that I've got Margot Robbie fatigue.
I'm going to guess there is a Fatty Arbuckle nod in there. From the name I am also guessing it draws stories from the book Hollywood Babylon.Kind of odd that the only real life person being portrayed is Irving Thalberg. Looks like the rest are loosely based on or composites of a number of golden age of Hollywood types. I guess Chazelle didn't want to ape Once Upon a Time in Hollywood too much? That's what this movie reminds me of (perhaps with the excess of Wolf of Wall Street).
