Amazon Prime has this feature and calls it X Ray:

It shows the profile photo and character and actor name of people in the scene, which is a nicer UI.

I think it shows soundtrack songs too.

Presumably this is from Amazon's IMDB so does the new age of LLMs mean you can generate a similar DB with no copyright worries?
