The trailer for the fourth series of Game Of Thrones has been revealed.

Scroll down to watch first official promo clip for the new season of the show. The show will premiere on Sky Atlantic on April 7 at 9pm, and will be broadcast just 24 hours after it is shown in the US on the HBO network. Game Of Thrones, which is adapted from George RR Martin’s series of fantasy novels A Song Of Ice And Fire, has been a huge hit since premiering in 2011 and has won numerous television gongs including Golden Globes, BAFTAs and Emmys.

The show’s fourth series will see an influx of new characters joining the cast, with Sherlock actor Mark Gattis and Gangs Of New York‘s Roger Ashton-Griffiths both joining the production. Meanwhile, the role of Prince Oberyn Martell will be played by Chilean actor Pedro Pascal. Pascal’s CV includes recurring roles on US TV series The Good Wife, Graceland and Red Widow. Prince Oberyn Martell is also known as The Red Viper. In the novels, he’s a lusty, hot-headed character with a quick wit and sharp tongue who’s rumoured to be bisexual.

In September last year, meanwhile, it was revealed that members of Sigur Ros will make appearances in the fourth season of the show. Their cameos came about as showrunners David Benioff and Dan Weiss are big fans of the Icelandic band and listened to their music while shooting previous series in Iceland.
