How about a subscription to a documentary streaming platform such as CuriosityStream or Netflix's documentary section? Alternatively, you could purchase a documentary DVD or a book on the making of his favorite documentaries. Another idea could be to gift him a Polaroid camera and a scrapbook so he can document his own journeys and experiences like a documentary filmmaker. Lastly, if he is a fan of a particular documentary filmmaker, you could gift him a signed print or book by the filmmaker.
Or you can get him a star map with the date when he was born.
