It is significant that the title is "The Chaperone" and not "The Dancer."
My wife and I watched this at home on DVD from our public library. Before I saw the movie I had no idea who Louise Brooks was. From Kansas and in 1922 at the age of 15 she, along with a chaperone, went to NYC to try out for a dance troupe. While her life was a rocky road she indeed did go on to dance and star in a number of silent movies in the 1920s and 1930s.
While her memoirs did mention a chaperone to New York nothing is known of her, so for this movie one is created, Elizabeth McGovern as Norma, and much of the story focuses on her, her life back home, her experiences in New York trying to find out where she came from because she was adopted as an orphan.
Haley Lu Richardson, who really is an accomplished dancer, is in the role of Louise Brooks, with he bob black haircut looking pretty much like Louise did back then.
This is a good movie, very well made with interesting stories.
