Jack Black has been working on his dark magic.

“Sorry, no gaming videos this week,” the actor-comedian warns as he prepares to belt out the “Game of Thrones” theme song parody posted to his JablinskiGames YouTube page.

The video then cuts to an animated graphic, followed by Black frolicking about on a rainy rooftop parking lot while wielding a Longclaw foam sword and wearing a Three Wolf Moon and red dragon T-shirt and a cloak.

The wacky track features him scatting like his life depends on it.

“Throne-y throne thrones,” Black sings while somersaulting, running, and then kneeling on his own Hollywood Walk of Fame star.

The video has racked up over 901,000 views as of this writing. The clip — which also showcases a closeup shot of Black’s hairy nipple — went viral as the much-debated series finale aired Sunday night on HBO.

“You and Chris Hemsworth should make a movie called The Rock Of Thrones,” comments one viewer. “Can’t believe Jablinski [single]-handedly saved game of thrones,” writes another.

At the 2:16 mark, the video takes a hard pivot away from “Game of Thrones” — and onto wrapping strawberries in Gouda cheese and then “creams and lotions,” including Jack Black “Dragon Ice Pain Relieving Cream,” which only coincidentally includes the funny guy’s name. (He’s not affiliated with the Jack Black grooming products brand.)

Near the end of the video at 10:50, Black plays a tiny “Hear Me Roar/Game of Thrones” music box and plays with a toy dragon.

“Love you GoT,” the end credits read, “you da best.”
