The first trailer for the hotly anticipated fifth series of Game Of Thrones is here - and it might just be the worst-quality promo you've ever seen.

Screened in a selection of Imax cinemas, the promo was captured by one sneaky filmgoer on his or her smartphone and is now all over the web.

It opens with Cersei Lannister, still grieving the murder of her son, telling brother Jaime: "Nothing's more hateful than failing to protect the one you love."

She later comments: "That little monster's out there drawing breath."

Meanwhile, Tyrion, who escaped execution at the end of last season, appears to meet up with Varys 'the Spider'.

While Tyrion seems to have turned his back on power plays, declaring "I will never sit on the Iron Throne", Varys is scheming as ever, musing "I believe men of talent have a part to play in the war to come".

He tells Tyrion: "The Seven Kingdoms needs a ruler loved by millions with a powerful army and the right family name."

"Good luck finding him," Tyrion answers.

To which Varys says: "Who said anything about him?"

The trailer also sees Little Finger telling Sansa Stark: "There's no justice in this world, not unless we make it. Avenge them."

While Khaleesi appears unstoppable as ever, announcing: "I'm not going to stop the wheel. I'm going to break the wheel."

The new season is expected to debut on Sky Atlantic on 13 April.
