I have a custom post type called: "movie" I have only 4 movies in my movies section in the site. inside each movie post type I want to display all other movies in a side list like so:

• movie 1
• movie 2
• movie 3
• movie 4

so the user can navigate from each movie page to all other movies.

I use this code to display the list of all of my "movie" post types:

<ul>
<?php $loop = new WP_Query( array( 'post_type' => 'movie', 'posts_per_page' => 4, 'order'=>'ASC' ) ); ?>
<?php while ( $loop->have_posts() ) : $loop->the_post(); ?>
    <li>
    <?php the_title( '<a href="' . get_permalink() . '" title="' . the_title_attribute( 'echo=0' ) . '">', '</a>' ); ?>
    </li>
    <?php endwhile; ?>
</ul>

So far it is very simple and working.

I would also like to add a "current" class to each item in the list that corresponds to the post I am currently reading. for instance if I am inside movie 3 I see this:

• movie 1
• movie 2
• movie 3
• movie 4

The problem is that unlike wordpress custom menu, no "current-menu-item" or other class is automatically generated.

any clue how I can accomplish that?
Thanks a lot.
