Instead of using two separate things for actor, post type and the taxonomy, you can use the custom field with ACF in movies and set the rules as “Post Type” equal to actor, then you don’t have to enter the actor names twice.
Also querying will become easier, because both of them will be linked to each other.
And then what you can do in the actor page is loop through the movies and use ‘get_field’ to find out which movies a particular actor is connected with.
