You can use single_template filter hook.

function load_movie_template( $template ) {
    global $post;

    if ( 'movie' === $post->post_type && locate_template( array( 'single-movie.php' ) ) !== $template ) {
        /*
         * This is a 'movie' post
         * AND a 'single movie template' is not found on
         * theme or child theme directories, so load it
         * from our plugin directory.
         */
        return plugin_dir_path( __FILE__ ) . 'single-movie.php';
    }

    return $template;
}

add_filter( 'single_template', 'load_movie_template' );

There are a few steps to create the custom quick edit box and custom column

1. create a custom meta key (assumed that you have 1 already)
2. add custom admin column title and data (assumed that you want to shows the custom meta key in the column, if not, you may also modify a bit of the logic to accomplish the same effect because the principal is the same)
3. add custom quick edit box
4. add save logic
5. load script to modify original inline-edit-post function in order to support custom meta value
6. prepare the script file
