The behind-the-scenes stories of Sung Yoo Ri's new movie "Older Sister" were revealed.

The first scene of the movie started with the filming of Sung Yoo Ri being slapped in the face. Even though her face was swelling, she continued to smile.

The movie officials said, "while we filmed in the summer, the camera stopped working due to the 95 degrees weather. Even in that situation, she talked with the other actors and continued to work with them. Even in the underwater filming that took 14 hours, she was more concerned about the other actors and staff members."

Actor Lee Joo Seung also punched a mirror for a scene in the movie and surprised the staff members.

The movie "Older Sister," is about an older sister named Yoon Hee (Sung Yoo Ri), who lives in guilt, due to the fact that her younger brother died because of her. She had one picture of him in her wallet and had it stolen by a high school student named Jin Ho(Lee Joo Seung), who she coincidentally met later on. They share their pains and help each other get passed them.
