Changing categories in menu

OK, I’ve almost completed my second menu, please look, http://www.fuximagazine.com/film/2010/06/04/karena-lam-decides-to-call-quits-on-her-acting-career/

However, I’ve tried many different solutions to change the menu options and have not had much look. Instead of repeating the top menu, I want this menu to show the child and grandchild categories of the specific category.

Could anybody please help me, or even tell me if this is at all possible?

My current menu code is as follows,

<div id="fuximenu">
	<?php if ($comfy['menu'] == true) : ?>
	<ul>
	<li<?php if(!is_category() && !is_page()) { ?> class="current-cat"<?php } ?>><a href="<?php bloginfo('home'); ?>/" title="Home"><?php print NAV_HOME; ?></a></li>
	<?php wp_list_categories('orderby=ID&order=ASC&depth=2&hide_empty=0&title_li=&exclude='.$parent['film']); ?>
	</ul>
	<?php endif; ?>
	</div>
