Wordpress custom listing page - .htaccess

Question

I have WordPress site that has films and actor custom post types. Also I'm creating relationship with films and actors.
I have a page to list films that related to actor. On this page visitors can see in which films actor take role.
This pages URL is like this:
http://www.mywebpage.com/actors-films/?id=123456
id refers to the actor, with this id I'm doing a query and showing it on the page.
also this page supports pagination, this URL works too:
http://www.mywebpage.com/actors-films/page/2/?id=123456
actors-film page is a page that uses a custom template, this template determines the actor id and shows his films.
Every thing works fine, but I want to change the URL a little bit SEO friendly.
I have tried many URL formats
http://www.mywebpage.com/actors-films/jim-carrey
I don't know why but this URL redirects to actors page.
http://www.mywebpage.com/actors/jim-carrey
http://www.mywebpage.com/actors-films/123456-jim-carrey
I have tried to catch this kind of URL with .htaccess but no way to catch it, it always shows a 404 not found.
So, I need to do a rewrite with pagination support, can you please suggest me a way to do this?
edit : here is my .htaccess file
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^actors-films/([0-9]*)\-([^/]*)$ ^actors-films/?id=$1 [L]
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
Edit : I have realized that not rules works for me :
example :
http://www.mywebsite.com/tex shows a 404 with this rule : RewriteRule ^/tex /index.php [L]

Answer 1

Here is the solution, create a page named
add_filter('query_vars', 'ap_register_query_vars');
function ap_url_redirect_rules(){
add_rewrite_rule('actors-films/([^/]*)','index.php?pagename=artist-film-list&actor_slug=$matches[1]','top');
flush_rewrite_rules();
}
function ap_register_query_vars($query_vars){
$query_vars[]='actor_slug';
return $query_vars;
}
Now we can call the url http://mywebsite.com/actors-films/john-doe
