‘Game of Thrones’ villain stars in SodaStream April Fools’ gag

Hafthór “Thor” Björnsson, better known to “Game of Thrones” fans as evil killer Gregor “The Mountain” Clegane, teams up with Israeli company SodaStream for an April Fools’ Day prank.

Ostensibly advertising a product called “Heavy Bubbles,” an ad released March 31 shows Björnsson attributing his great strength to the new brand of sparkling water, which appears to be sold in dumbbell-shaped bottles. He then directs viewers to the website heavybubbles.com.

But anyone trying to purchase the water via the website receives a message reading: “Why do you believe such thing? It makes no sense. With SodaStream you don’t carry plastic bottles. You don’t sweat and you make sparkling water from normal water. At home, like me.”

Admitting that the ad was a joke, SodaStream CEO Daniel Birnbaum says the company “wanted to emphasize how ridiculous it is to continue to carry bottles home from the supermarket, so we came up with this crazy, out-of-the box campaign,” according to the PR Newswire website.

Bjornson, who joins Black Widow actress Scarlett Johansson as a famous face of the brand, says: “I’ve been using SodaStream since I was a kid and was therefore thrilled to collaborate in this video. I’m always open to new techniques for exercising, but you’ve got to admit that carrying bottles home from the supermarket is a hassle and actually pretty stupid when we have an alternative such as SodaStream.”
