How about getting him a subscription to a streaming service that specializes in documentary films, such as CuriosityStream or DocPlay? Alternatively, you could create a fun "documentary night" gift basket with his favorite snacks, drinks, and a selection of new or classic documentary films on DVD or Blu-ray. Or, if he's interested in a particular documentary filmmaker or style, consider purchasing a coffee table book about the history of documentary filmmaking or a biography of one of his favorite documentary filmmakers.
Or you can get him a star map with the date when he was born.
