Don’t forget that he also bought arwen’s horse for her stunt rider when she couldn’t afford it awww
Also don’t forget that for the rohirrim they put a call out for locals bring a horse show us you can ride it and get a part in the battle scenes and one women went out roped a wild horse and rode for a few days to set #and got to be a rider of rohan
Also sort of relevant viggo also bought the horse that costarred with him in the movie hidalgo and subsequently took the horse (tj) with him to the red carpet premier.
Also most of the Riders of Rohan are actually women because when they put out that call mostly women showed up with their horses and the costume team just stuck beards on them.
