Translation:There have been many movies made about Andersen's fairy tales.
The pronunciation of word "lavet" should be updated to match how it is said by Danish.
Yeah, the pronunciation is kinda off here. It is more like "lad" with a soft d at the end.
There are several ways to translate this and they all sound more natural than the answer given.
Mange film er lavet om Andersens eventyr.
It sounds a little Yoda, but it's not a wrong sentence.
What's wrong with "There are many films made about Andersen's fairy tales"?
