How about gifting them a personalized adventure movie-style poster that features them and their spouse? You can hire a graphic designer on websites like Fiverr or Etsy to create one, or use a website like Canva to make one yourself. Alternatively, you could create a "date night in" gift basket filled with adventure movies, popcorn, and other movie night essentials. Another option could be gifting them a certificate for an adventure activity such as ziplining or rock climbing.
Or you can get her/him a star map with the date of the wedding.
