One idea could be to purchase a subscription to a documentary streaming service, like CuriosityStream or DocPlay. Another idea could be getting him a DVD or Blu-Ray copy of his favorite documentary film, or a box set of documentaries on a particular topic or filmmaker. Additionally, you could look into purchasing tickets or a pass to a documentary film festival in his area, if there are any coming up soon. Finally, if he also enjoys reading, you could get him a book on the making of a well-known documentary or on the history and impact of documentary filmmaking.
Or you can get him a star map with the date when he welcomed you in this world.
