How about a collection of his favorite fantasy movies on DVD or Blu-ray? You can also get him some movie-related merchandise such as a framed poster or a t-shirt featuring his favorite characters. If he enjoys reading, you could also get him a book in the fantasy genre or a subscription to a fantasy magazine. Another idea could be tickets to a fantasy convention or festival where he can meet his favorite actors, directors, and writers in the genre.
Or you can get him a star map with an important date you share.
