'The Glory' star Song Hye-kyo says that the show's director kept telling her to 'act even crazier' when her character is 'declaring war' on her old bullies

• Song Hye-kyo said there was one scene in "The Glory" where she was told to "act even crazier."
• In the scene, Song's character Dong-eun confronts her childhood bullies in their old gym.

"The Glory" star Song Hye-kyo said that, during one scene in "The Glory," she was continuously told to "act even crazier" until she reached a level that the director found appropriate.

"The Glory" follows Moon Dong-eun (played by Song), a woman who resolves to take revenge on her childhood bullies through a painstakingly planned, multi-year plan. In the show's third episode, Dong-eun confronts her old bullies in the same school gymnasium where they repeatedly assaulted her years prior.

In a Netflix Korea commentary video, Song and screenwriter Kim Eun-sook reflected on the scene, which Kim called "horrifying" and said Dong-eun was basically "declaring war."

"When we were filming that, I wasn't sure how much she was expecting," Song said, referring to Kim. "I wasn't sure how far I should go, but the script said... I'm not sure if I can say this, but it said I should act like a crazy bitch."

In the scene, the group of bullies gathers at their old school to celebrate the group's ringleader, weathercaster Park Yeon-jin (Lim Ji-yeon), who is receiving an alumni award. Dong-eun confronts them before the ceremony, and unnervingly claps and cheers for Yeon-jin when she receives the award while the rest of the audience is silent.

"I had in my mind how crazy I should be, so we did one take of it, but then, Director An came and said, 'Act even crazier,'" Song said, referring to director and producer An Gil-ho. "So I think the intensity kept going up."
