Custom Post Type Page 404

I’ve been following along with a tutorial for creating custom post types and keep getting stuck. For some reason, I get a 404 page when trying to show a page for the new post type.

class JM_Movies_Post_Type{
	public function __construct()
	{
		$this->register_post_type();
	}

	public function register_post_type()
	{
		$args = array(
			'labels' => array(
				'name' => 'Movies',
				'singlar_name' => 'Movie',
				'add_new' => 'Add New Movie',
				'add_new_item' => 'Add New Movie',
				'edit_item' => 'Edit Item',
				'new_item' => 'New Item',
				'view_item' => 'View Movie',
				'search_items' => 'Search Movies',
				'not_found' => 'No Movies Found',
				'not_found_in_trash' => 'No Movies Found in Trash'
			),
			'query_var' => 'movies',
			'rewrite' => array(
				'slug' => 'movies/',
			),
			'public' => true
		);
		register_post_type('jm_movie', $args);
	}
}

add_action('init', function (){
	new JM_Movies_Post_Type();

});

Any ideas where my error is?
Thanks

[No bumping, thank you.]
