You only need to make out things a little. First of all, run the query:
<?php $loop = new WP_Query( array( 'post_type' => 'films', 'post_child' => 0, 'posts_per_page' => 8,'orderby' => 'date', 'order' => 'ASC', 'film-categories' => 'blu-ray' ) ); ?>
Then check if there is something:
<?php if ($loop->have_posts()) { ?> <div class="bigRedStrip"> <h2>Available Now!</h2> </div> ...
And if so, just iterate over the messages:
... <ul> <?php while ( $loop->have_posts() ) : $loop->the_post(); ?> <li> loop stuff here </li> <?php endwhile; ?> </ul> <?php } ?>
