Really? What are they?
There was a (successful) staging of Othello to various parts of Jerry Goldsmith film music, including such scores as THE WIND AND THE LION and THE SWARM and ALONG CAME A SPIDER.

And the Columbus ballet staged “Belling the Slayer” to the music of “Capricorn One” by Jerry Goldsmith some years ago.
There are some more.
As I said, “ballet music” is no more a genre than “film music”, can be basically any type of music. And since a lot of ballet music sounds like film music anyway, it follows only logically that a lot of film music sounds like ballet music.
