How about gifting him a collection of his favorite action movies? You could put together a curated box set of Blu-rays or DVDs with his top 5-10 favorite action movies, along with some themed snacks like popcorn or candy. Another idea is to surprise him with tickets to an upcoming action movie that he's been wanting to see, or an advance screening of a new release. If you're feeling creative, you could even make a homemade movie-themed gift basket with items like themed t-shirts, posters or action figures.
Or you can get him a star map with the date of your anniversary.
