Nothing really of value here, unless someone can figure out what sort of things those firearms and visual effects companies specialise in.
Locations don't really mean much. As most of us are aware, all sorts of locations are used to replace the real ones. Tunisia represented a desert on a different planet in a certain seventies science-fiction film.
As for horses, I don't mind them. Either they're still used in the future for riding around on or they're being used to represent old times. Or, like the use of a small dog in '
Alien 3', they're trying to outfit them in some sort of costumes for some quick shots of quadruped creatures.
In either case, it doesn't inform us very much about the story.
