Hey Alex, happy new year to you too.

To answer your questions:

1) Custom post type called movies (made with th plugin “CPT UI”)
2) Do you mean the ajax effect? You must enable ajax under the display results tab, either will allow for reloading results without refreshing the page, however “as archive” will allow for more seamless integration like the movies demo.
3) You would create another taxonomy – please see here:

Hope that helps!

Hey Alex

I gave pretty in depth breakdown of that setup recently:
