And hello to you, well in general I do not understand why you do not get anything interesting, because in the search engine is quite a lot of good options, just try to google yourself somehow, rather than wait that the option will come up by itself. Of course, if you have already tried to search intentionally, but nothing interesting came up, then personally I can advise you to look at the options of movies about dance here
https://movieslist.best/list/movies-about-dancing/ . There is a big enough choice on the site, each of the movies has a detailed description, so you don't have to "point your finger in the sky" and you can make an informed choice. I hope I was able to help in this matter. Good luck!
