AceShowbiz - Ahead of the premiere of final season of "Game of Thrones", fans are offered new details of the hit HBO series. Star Emilia Clarke, who will reprise her role as Mother of Dragons Daenerys Targaryen in the upcoming eighth and final season season, hinted at the ending of the series while attending the 91st Academy Awards on Sunday, February 24.

"Shock," the 32-year-old said to Ryan Seacrest. "It's going to be huge."

In addition, Emilia, who debuted her new haircut at the Oscars, revealed that the medieval series took a while to complete filming the final season due to the intriguing finish. "It took us a very long time for us to shoot this one for a very good reason," she explained.

In related news, HBO has unveiled new footage of the new highly-anticipated season. The video comes as a sneak peek of all of the network's upcoming new shows and new seasons. Though it's only 3 seconds long, the new video teases a seemingly interesting storyline for Arya Stark (Maissie Williams).

A dragon is seen flying over troops before the scene cuts to Arya who looks strangely ecstatic while looking at the sky. It seems like the scene is taken during the time when she first sees the dragon.

Fans can also see a glimpse of the wall crumbling. It also features a look at some of the major players in the upcoming battle: Jon Snow (Kit Harington), Daenerys Targaryen, the Night King, the dragons and Tormund (Kristofer Hivju).

Previous reports suggested that Sansa Stark (Sophie Turner) would don an armor in the new season. While Robin Arryn (Lino Facioli) and Edmure Tully (Tobiaz Menzies) allegedly would make an appearance in the premiere episode of season 8. Other supporting and secondary characters who are expected to appear in the first episode of season 8 are Anton Lesser as Qyburn, Hafpor Bjrnsson as the Mountain, and Pilou Asbæk as Euron Greyjoy. Rupert Vansittart, Bella Ramsey and Richard Rycroft, who portray Yohn Royce, Lyanna Mormont and Maester Wolkan respectively, are also among characters on the list.

Also starring Lena Headey, Peter Dinklage among others, the eighth and final 6-part season of "Game of Thrones" will premiere on Sunday, April 14 on HBO.
