How do I get the child category posts from a custom post type?

For the Now showing add 'cat' => 6 to the query array like so:

    $args = array( 'post_type' => 'movies', 'paged'=>$paged ,'cat' => 6);

and for the Coming Soon add 'cat' => 7 so:

    $args = array( 'post_type' => 'movies', 'paged'=>$paged ,'cat' => 7);

but from what i can see you got it working:
