Add categories to Green Day
The existing categories for this option are listed under the text box. If you think some more should be added, maybe a movie that should also be listed as a horror, or a singer who's done some acting, just type your suggestions into the box. Some related suggestions may appear too - just click whichever one you think should be added. You can add them one at a time or all at once, just separate each suggestion with a comma. Thanks!
