On January 16, the actor's agency, Management Soop, revealed behind-the-scenes photos of Gong Yoo in action.

In the still cuts, Gong Yoo emerges from the dark against the bright city lights of Seoul, his face hidden behind a black mask. Despite the cold weather and windy conditions, the mask clearly wasn't able to disguise the actor's 'handsomeness'.

Dressed in all black, Gong Yoo gave a sleek goblin pose, while wielding a sharp sword ready to strike at his opponent.

Stay tuned for this week's finale, as 'Goblin' draws to a close!
