Advanced Search - Actor criteria

Currently, the Advanced Search has so many options/criteria for TV series and films; I'd like to see many more options related to the actors, such as Birthday (year, month, day), From (country, city), School (college, high school, workshop), Interests (hobbies, sports), Mentor/Inspiration, Favorite Films, etc. In the Trivia section, all these items are listed; and it'd be nice to be able to search/filter/sort by these criteria.
