Fans of the George RR Martin novels, on which the HBO show is based, will know that the figures are in fact the Seven - or the gods of Westeros.
Appearing on Downhill beach, the statues are an unfamiliar addition to the oft-photographed landscape and yet look quite at home beneath Mussenden Temple on the nearby cliff-top.
Locals and those eager for a sneak peek behind the scenes of filming alike have been left intrigued by the goings-on.
Amanda Killen, who is originally from Australia but lives in Castlerock, snapped pictures of the statues which immediately attracted thousands of hits from online viewers around the world.
"Castlerock is a very small community and, all of a sudden, Game of Thrones has put us in the spotlight," she told UTV.
Amanda is delighted to see Northern Ireland getting such positive publicity and added: "Suddenly people are sitting up and taking notice of Northern Ireland."
But while there's plenty of curiosity about having a film set on the doorstep, it seems local people are a little shy about intruding - perhaps to the relief of the crew.
"People do seem quite reticent about it," Amanda said, explaining that she had taken some of her photos from the cliff-top as parts of the beach were closed off during filming for safety.
"I saw Mission Impossible being filmed in Sydney and couldn't believe how many people turned up for a look - I was surprised they got any filming done!"
Game of Thrones is currently filming its second series, both at Belfast's Paint Hall studios and at a number of other locations - but with Northern Ireland's film industry positively booming, there's no telling what sights may greet locals in the future.
