Creating 3rd level pages

Hi everyone,

need a helping hand as i am stuck.

i am a novice with wordpress and I have used a plugin to create a custom post type called Movies and within that i have created taxonomies called actors, actresses and directors.

I am having pages to show the listing of all the movies, actors and actresses and directors respectively as:
mysite.com/movies/
mysite.com/actors/
mysite.com/actresses/
mysite.com/directors/

when i click on any movie name it takes me to the particular page of the movie with the details of that movie and my url becomes:
mysite.com/movies/movie-name

when i click on a particular actor for that movie it takes me to:
mysite.com/actors/actor-name/

this is all fine. now my problem is that i want to create a sub page for the particular actor so that when i click on the movies link on that particular actors page it should take me to a different page and my url should become:
mysite.com/actors/actor-name/movies/

I am unable to find a solution as to how to create a sub level page for each of the particular actor, actress and directors.

Any help would be highly appreciated.

one more thing that i forgot to specify is that when i go to mysite.com/actors/actor-name/movies/ page it should display movies that are related to that particular actor only i.e., i dont have to enter specific movies for each actor as the movies have already been entered in the custom post type.
