Production for "Game of Thrones" season 6 has just wrapped, which means that the finale for the season is now locked in. With the HBO fantasy series overtaking the George R.R. Martin saga it was based on, there's no telling what will take place upon the season's end.

But thanks to director Miguel Sapochnik, fans now have an idea that it will somehow involve the ever-menacing White Walkers. Just recently, Sapochnik shared on Twitter a photo of a clapperboard for episode 10 aka the finale, dated Nov. 3.

The spoiling part comes from the description, which says"White Walker unit." This had media outlets believing that the finale will involve the terrifying undead of the cold, which already scared the living daylights out of some fans in the last season of "Game of Thrones."

Knowing that Fabian Wagner, whose genius made happen the breathtaking battle of Hardhome in season 5, is in charge of the photography in the "Game of Thrones" season 6 finale suggests that this would be another grand spectacle to look forward to.

Just recently, leaked set photos indicate that Jon Snow and Sansa Stark will reunite to battle the Boltons in the new season. Many believed it would be the highlight of the season but the revealed involvement of the White Walkers show that HBO is going big next year.

In related news, HBO recently denied reports that Bollywood actor Neil Nitin Mukesh will be in "Game of Thrones" season 6. This is after the "Prem Ratan Dhan Payo" star told Mumbai Mirror that stunt director Greg Powell was so impressed with his sword skills he offered him a role.

Mukesh eventually added via Independent that "Nothing is confirmed so far. All I can do is keep my fingers crossed. Game of Thrones is one of my favorite series."

"Game of Thrones" season 6 premieres spring next year.
