The documentary video, "The Dancer," follows the young student Katja Bjorner at the Royal Swedish Ballet school. Does she still dance? And how did her career develop?

Katja Björner is indeed still dancing with the Royal Swedish Ballet. She is now a soloist.
The film "Dansaren" (in Swedish) is about ten years old and according to my daughter whom I consulted on the matter, Katja ought to be between 25-30 years of age.
I did see the film with DD, but must confess that I do not remember much.
The Royal Opera House does have a site, unfortunately only the opera section has an English version, the ballet section is only in Swedish. This surely must be considered unfair!
Most dancers have their portraits there with a list of roles.
If you need any translation, please do not hesitate to ask me!
