It's been long, hard road for Jon Snow, but Ser Davos believes it might earn him glory in the end -- in the form of acting awards.

Speaking with The Hollywood Reporter, "Game of Thrones" actor Liam Cunningham described the monumental work that went into this week's highly anticipated episode, "The Battle of the Bastards," which features the long-brewing showdown between Jon Snow and Ramsay Bolton.

Cunningham, who has counseled a number of Westerosi leaders since Season 2 of the acclaimed HBO drama, praised the production team's immense scope and dedication to making this season's penultimate episode the biggest they possible could.

"HBO threw everything including the kitchen sink at it," he said. "It's one of the most expensive episodes of television ever made. We spent roughly a month just doing this particular battle. It's absolutely extraordinary, to be honest with you."

It's not just the numbers that are staggering, but also the caliber of acting. Cunningham singled out star Kit Harington's transformation, admitting he would be "very, very surprised if Mr. Harington isn't taking up a statue at the end of this."

"The amount of stuff I saw Kit doing out there … his fight work. His stunt work. He's like a dancer when he moves," the veteran actor said. "I think he's blossomed from a young man into this fantastic character that he's playing in this."

"Game of Thrones" airs Sunday at 9 p.m. ET/PT on HBO.
