Linking posts

Hi all,

I hope I’m posting in the right place.
I have a dilemma and I don’t know exactly how to proceed.
Using the Custom Post Type UI plugin I’ve created a new Post Types menu and taxonomies to save film actors in different categories.

Then when I post an article (lets say a movie review) I would like to have the ability to link that article to an existing actor (if it’s possible with an ajax suggestion). That when I access an actors page to be able to print all the articles that are linked to him.

I search for a plugin that will add an ajax search with terms from a category when adding tags to an article but I didn’t find any. If you can help me with an idea on how to do this or with a tutorial I would be more than grateful.

Thank you!
