The scene in "Game of Thrones'" season seven finale in which Jon Snow explains the importance of keeping his word was filmed on the same day Donald Trump won the 2016 presidential election, according to one of the cult television show's stars.

"That speech that Jon Snow gave about the nature of lies and what's been said, and what happens if we don't stick to our word — we filmed that on exactly the day that a certain POTUS was elected and it had incredible resonance while we were filming it," Liam Cunningham, who features as Snow's adviser Davos Seaworth, told Variety.

Cunningham, an Irish actor, said the election results had been announced the morning that filming of the dialogue — part of negotiations between key protagonists regarding a possible truce of the program's fictional civil war — was due to begin.

"We may have been rehearsing that scene," Cunningham continued. "But that was the first time that Kit Harington (who plays Snow) had said those words on that platform in that scene. So it had a certain resonance, I'm sure you'll understand."

In the script, Snow tells the other characters that "when enough people make false promises, words stop meaning anything."

President Trump has been slammed by his critics for being loose with his words, with supporters urging them "to take him seriously, but not literally."
