Sophie Turner went to her first ever IMAX screening on Thursday night, seeing "Game of Thrones" alongside fans and the producers of her HBO show.

before sitting down to watch "GoT" Season 4, Episodes 9 and 10, alongside Executive Producers David Benioff and D.B. Weiss.

It was funny because from Season 1 upwards, right to the beginning of Season 4, I was just like surrounded by a ton of actors, which was incredible, and I loved it, and then suddenly going to literally just like me and Aidan was so intense, but it was just a change and it was so nice," Sophie said. "And Aidan's so talented. It felt like we were the gruesome twosome."

"Season 5 is pretty massive. ... The storylines are just insane this season. Arya's storyline is incredible. I'm obsessed with my storyline. And it's so action packed as well this season," she said.
