I was thinking it’ll be nice to have a sub tab under Movies tab where a user can view the list of unique actor that appeared in his/her watched movies.
The list would be sorted according to the actor/actress that appears the most in all watched movies.
That is, if actor X appeared in 7 out of my 15 watched movies, that actor would appear at the top of this list, followed by actor Y who only appeared in 4 out of my 15 movies.
