J. Kim Murphy Animals rights activists have condemned the death of a horse on the set of Prime Video’s “The Lord of the Rings: The Rings of Power.” On March 21, a horse suffered cardiac arrest ahead of rehearsals on the production of the fantasy streaming series. Amazon Studios released a statement confirming the situation on Sunday morning. “We are deeply saddened to confirm that a production horse died on 21st March,” an Amazon spokesperson said. “The incident took place in the morning whilst the horse was being exercised prior to rehearsals. The trainer was not in costume and filming had yet to commence. Both a veterinarian and a representative of the American Humane Association were present at the time. The independent necropsy has confirmed that the horse died of cardiac failure.”
