Stranger Things creators Matt and Ross Duffer felt that Suzie’s reveal needed a dramatic beat and had wanted Materazzo, who’s sung on Broadway, to show off his musical chops. “We went through all the various songs they could sing,” Matt tells EW. “At one point they were going to sing the Ent song from Lord of the Rings. Then we were like, ‘Oh, well, Amazon is making Lord of the Rings, that’s probably not going to go over well with Netflix.’ Then we came up, I think it was Curtis, our writer, who came up with I think a better idea, which was The NeverEnding Story theme song.” Adds Ross, “Certainly filming that sequence, that was some of the most fun we had on this season. It was just so great.”
