Adding more taxonomies (Tags like)

Hi all,
I work with WP 3.5.1 hosting on my local PC.
I added the following code in function.php hopping that I’ll find 2 more taxonomies,in aditions to Tags-actors and producers, but nothing happens.
Modifying to a different theme and then back to my theme didn’t help(my theme is TwentyTen)

Can someone advise please?
Thanks in advance

function create_my_taxonomies() {
register_taxonomy(‘actors’, ‘post’, array(
‘hierarchical’ => false, ‘label’ => ‘Actors’,
‘query_var’ => true, ‘rewrite’ => true));
register_taxonomy(‘producers’, ‘post’, array(
‘hierarchical’ => false, ‘label’ => ‘Producers’,
‘query_var’ => true, ‘rewrite’ => true));
}
add_action(‘init’, ‘create_my_taxonomies’, 0);
