A great idea would be to get your husband a documentary film festival pass. This would give him the opportunity to see multiple documentary films over a few days, and he may discover new films and filmmakers that he loves. Alternatively, you could get him a subscription to a streaming platform that offers a wide selection of documentaries, such as Netflix or CuriosityStream. Another option is to get him a book that delves into the making of his favorite documentaries, such as "The Making of Star Wars" or "Hitchcock/Truffaut: The Definitive Study of Alfred Hitchcock."
Or you can get him a star map with the date when he was born.
