Apparently, the Battle of the Blackwater orchestrators wanted the mastermind behind The Battle of Evermore within their ranks at one point. That’s right — Mr. Robert Plant himself was asked to join the Game of Thrones cast. Granted, it was only a small cameo that they wanted him for, so the Led Zeppelin frontman didn’t stand to become the third piece of a Jon Snow/Daenerys Targaryen love triangle, and certainly wasn’t asked to slay The Mountain in a one-on-one fight to the death (per Led Zeppelin News).
It really does make sense, if you think about it. Plant used to sing about the darkest depths of Mordor, grand odysseys across vast plains, vikings, and ethereal worlds beyond our own dimension. All the same, he unfortunately didn’t share the same enthusiasm for a prospective Thrones guest spot as the show’s production team did. After he was asked to appear in an episode, Plant turned the offer down promptly (per Screen Rant).
