KBS drama "Mary Stayed Out All Night" is maintaining one digit viewers ratings and cannot seem to raise it. However, the actors are working as hard as ever. According to AGB Nielson Media Research, November 29th's episode of "Mary Stayed Out All Night" had a poor national rating of 6.6%. Despite this, Moon Geun Young is showing her willpower by focusing on her acting, as photos of Moon filming in the rain on November 27th were recently revealed. In the film stills, Moon is running in the rain without an umbrella while talking to someone on the phone. In another still, Moon is avoiding the rain in front of Jang Geun Suk's house. On this day's filming, Moon received applause and cheers from the staff for delivering perfectly even in the sub-zero temperature rainy weather. One staff member said, "The temperature suddenly dropped below zero, and we had a rain scene planned in our rigorous schedule. We were worried that Moon Geun Young would catch a cold or something, but seeing the effort she put in for a perfect scene showed that she truly is an actress sent from heaven." The staff continued complimenting, saying, "Her small body is always brimming with energy and enthusiasm. It's touching." Moon stated after filming, "The temperature suddenly dropped, so the weather was very cold. A water sprinkling truck sprayed water, so the staff on the scene also suffered immensely from the cold. I get strength because I'm not the only one suffering; both staff and actors work together and encourage each other when we film." Source: Newsen Photo: Newsen
