Game of Thrones brought the ice dragon to life in a very odd but hilarious way.
Viserion's roar is actually a group of intoxicated fans yelling.
The show's sound designer, Paula Fairchild, met a bunch of fans at the Con of Thrones convention in Nashville and asked them for help.
A fan has revealed Paula later recorded them drunk without telling them what is was for.
She told Winter Is Coming:
"We just, like, took an evening, and drank a f**k-ton of gin and screamed our hearts out."
"And then when it was all over, she leaned over and was like, 'You guys are the ice dragon.'"
Mad!
