Aidan Gillen has said "no one could have predicted" the success that is fantasy series Game of Thrones.
The Dublin actor, who played Petyr 'Littlefinger' Baelish in the hit HBO show, told the Herald that the programme, now in its final series, was a "one-off".
He added that its makers had invested passion and money into the series.
The 50-year-old said he had been tuning in since the show returned to the small screen two weeks ago.
"I watched episode one and a bit of two. It's all good so far," he said.
"It's a one-off for sure. These things come along every 10 years but no one could've predicted it'd be a fantasy epic.
"It is done in a different way with passion and a big production behind it. They put their money on the table with that one."
The Drumcondra star has previously admitted he doesn't know how the series will end, although some fans are speculating that Littlefinger might make a return from the dead by the final episode.
"I'm clueless," Gillen said when asked who would claim the Iron Throne.
"There's 10/1 on Paddy Power or William Hill on Petyr Baelish being the ultimate victor in Game of Thrones. What's that about?
"To be able to finish this off at all is going to be quite a task. I don't doubt they can do it in some style and some surprising and stunning fashion, so let's hope that's what happens."
Game of Thrones has had a triumphant return, with the opening episode watched legally by 17.4 million people in the US and many more across the globe.Juicy
The second instalment of the final season aired earlier this week, as the characters prepared to fight the Night King.
It wasn't without its juicy moments though, as 18-year-old Arya Stark - who finished off Gillen's character in season seven - had a raunchy sex scene with Gendry, played by Skins actor Joe Dempsie.
Many viewers found the scene "uncomfortable" but Maisie Williams, who plays Arya, had the last word: "If you feel uncomfortable just know that my mother and my stepdad and my two sisters and my four brothers have all probably watched this too."
