For IMDB that's not possible. Does not provide such details.
Only would be possible for TMDB and you would need to use URLs like this:
Code:
https://www.themoviedb.org/person/1356210
However TMDB sometimes does not have some movie details at all.
But even then it would a lot of work to do. Is it really needed? I don't think people would ever click on those links to go to TMDB. They only want to download.
You should already have IMDB link in your post and actors names (that's supported). They can go there to check more details if they really want.
