Fan Casting Balder the Brave in God of Thunder Universe

I just heard that Matt Damon has joined the cast of Thor: Love and Thunder. I'm calling it now he will be Balder the Brave. Damon and Hemsworth share a good friendship through their past works together. Balder is the brother of Thor in the comics. I don't know if they will explore that route, but I do really like exploring the idea of Thor finding out his mother really is. As in the comics, his mother is not really Frigga, but Gaea.
