Part of Game of Thrones' endgame is the constant growth of Daenerys' three dragons, Drogon, Viserion and Rhaegal. In this summer's Season 7—the series' penultimate run—they'll be the size of jumbo freakin' jets.

“The dragons this year are the size of 747s," director Matt Shakman tells Entertainment Weekly. "Drogon is the biggest of the bunch—his flame is 30-feet in diameter!” The mag notes that such planes are "about 230 feet long with a 210 feet wingspan."

Seven hells

Game of Thrones Season 7 hits HBO on July 16, the network flashily announced last week.

Shakman is a TV-directing veteran with credits on It's Always Sunny in Philadelphia, Fargo, Mad Men, House and Six Feet Under, among many others. He helmed the fourth and fifth episodes of Thrones' seven-episode seventh season, and as we all know, the episodes leading up to the finale are often the craziest.
