Add custom post types stats to a custom dashboard widget

Lokks like you have a function declared inside another function, your code is wrong, try this:

// wp_dashboard_setup is the action hook
add_action('wp_dashboard_setup', 'mycustom_moviestats');

// add dashboard widget
function mycustom_moviestats() {
    wp_add_dashboard_widget('custom_movie_widget', 'Movie Stats','custom_dashboard_movie_list');
}

function custom_dashboard_movie_list(){

    $args = array(
        'public' => true ,
        '_builtin' => false );
    $output="object";
    $operator="and";
    echo '<table>';
    //loop over all custom post types
    $post_types = get_post_types( $args , $output , $operator );
    foreach( $post_types as $post_type ) {
        $num_posts = wp_count_posts( $post_type->name );
        $num = number_format_i18n( $num_posts->publish );
        $text = _n( $post_type->labels->singular_name, $post_type->labels->name , intval( $num_posts->publish ) );
        if ( current_user_can( 'edit_posts' ) ) {
            $num = "<a href="https://wordpress.stackexchange.com/questions/17625/edit.php?post_type=$post_type->name">$num</a>";
            $text = "<a href="https://wordpress.stackexchange.com/questions/17625/edit.php?post_type=$post_type->name">$text</a>";
        }
        echo '<tr><td class="first b b-' . $post_type->name . '">' . $num . '</td>';
        echo '<td class="t ' . $post_type->name . '">' . $text . '</td></tr>';
    }

    //loop over all taxonomies
    $taxonomies = get_taxonomies( $args , $output , $operator ); 
    foreach( $taxonomies as $taxonomy ) {
        $num_terms  = wp_count_terms( $taxonomy->name );
        $num = number_format_i18n( $num_terms );
        $text = _n( $taxonomy->labels->singular_name, $taxonomy->labels->name , intval( $num_terms ));
        if ( current_user_can( 'manage_categories' ) ) {
            $num = "<a href="edit-tags.php?taxonomy=$taxonomy->name">$num</a>";
            $text = "<a href="edit-tags.php?taxonomy=$taxonomy->name">$text</a>";
        }
        echo '<tr><td class="first b b-' . $taxonomy->name . '">' . $num . '</td>';
        echo '<td class="t ' . $taxonomy->name . '">' . $text . '</td></tr>';
    }
    echo '</table>';
