"I knew that a few months ago that they were interested in putting him in the show and I'm glad he did it. It'll be great," she said.

However, McGregor's appearance in Game of Thrones Season 7 is only short-lived as he will only has a cameo role. Fans won't even see him talk, thus he will just literally appear.

Moreover, there are also claims that the seventh installment of the television adaptation of George R.R. Martin's A Song of Ice and Fire will only have seven episodes. The usual number of chapters one season has is 10 but this time, fans will only witness seven.

But, Iain Glen, who plays Ser Jorah Mormont, gives everyone good news when he revealed that the production team gives just the same time filming the show's new chapter in spite of having fewer episodes.

Glen revealed that people behind Game of Thrones Season 7 "are taking the length of time" to shoot 10 episodes with just seven episodes this year and six in the coming year. "There are fifteen more hours left in Thrones as we understand it, but that may change," he said.

He also said that the reason for longer shootings might be because of the show's set pieces and their extraordinary environment. In an analyzation made by BGR, it noted that if Game of Thrones Season 7 still has 15 hours left with only 13 episodes, this might mean that there will be episodes that will be seen longer or extended.
