The upcoming KBS drama series, "The Musical", revealed cuts of Goo Hye Sun dancing in the middle of a busy street with fellow castmate�Park Kyung Lim. In another picture, Goo Hye Sun seems to be dancing a rather powerful dance while dressed in masculine attire. Rumors say that she had to dance into the early mornings in order to shoot that one scene. The producers revealed, "It must've been hard for her to concentrate because of the crowd that surrounded her, but she was very professional and focused on every second of the choreography." "The Musical" will be released in the middle of October after the filming wraps up on New York's Broadway.
