With just two seasons left, Game of Thrones fans are desperate to see feuding brothers The Mountain and The Hound face off before the series ends.

Speaking exclusively to Digital Spy, actor Hafþór Júlíus Björnsson - who plays the towering Mountain - revealed that he's aware of the expectation for what's been called 'Cleganebowl'.

"I cannot [read all of the fan theories] - it's very hard for me to follow up everything that my fans comment," he said. "But I've been seeing some of them and I did notice a lot of people were talking about the Cleganebowl - people were waiting for me and my brother to fight.

"There's a lot of expectation from the fans to see that happen - obviously I cannot comment on that... you're just going to have to see what's gonna happen!"

So a big fat No Comment, then - but we're taking it as a good sign that Björnsson, and so we're guessing the rest of the GoT team, know how badly we want to see Sandor (Rory McCann) duel with Gregor.

In case you'd forgotten, the warring siblings did briefly spar way back in season one - but at the time, Gregor was played by Conan Stevens.

Hafþór Júlíus 'Thor' Björnsson has teamed with SodaStream for a new commercial - also starring Game of Thrones actress Hannah Waddingham (Septa Unella) - which encourages people to drink more fresh tap water instead of buying plastic bottles that contaminate the planet.
