Asks the Slate writer Nadira Goff, in "How Emma Stone and Mark Ruffalo’s Delightfully Weird Dance in Poor Things Came Together/Choreographer Constanza Macras on the standout scene, working with Yorgos Lanthimos, and expanding the idea of what dance is."
The choreographer answers: "It’s described in the script as a dance that is really going off because she’s just finding out [about dance]. So, with that in mind, I tried to create. [The director] was not convinced about some things; it looked too much like acting. When we passed it to the actors, then it grew and took shape. Emma Stone also had really good suggestions about her character because she was working, already, on this way that she moves. She brought in locking the knees. That gave shape to this dance as well."
Stone's character is a Frankenstein creation, so we may well compare the dancing to the Frankenstein in "Young Frankenstein":
That Frankenstein monster is able to dance smoothly, but his singing is very rough. That's the joke, and that gets to the question I was googling when I found that Emma Stone dance: Why do dancers always try to look as though what they are doing is very easy (for them) and pure joy (for them) while singers often act as though it's quite difficult and even painful? That's a big difference between singing and dancing, and I don't think it's because singing is more arduous and hurtful. Perhaps it's because the opposite is true, and the dancer must hide his feelings lest the audience turn away. But we don't turn away when a singer displays a horrible struggle and deep pain. We like that. What's our problem?!
I formulated my question after watching Fred Astaire and George Murphy in the first part of "Broadway Melody of 1940" (now streaming on the Criterion Channel). The first musical number is "Don't Monkey With Broadway" (modeling, for future satirists, how 2 men dance together in formalwear while wielding canes):
The men are unhappy with their job. We see them complaining back stage before they stride out beaming with joy — joy that does not exist but that the audience demands.
