It was announced a while back that Goo Hye Sun, after doing everything from acting to writing a book, would be directing a movie titled Yosul or Magic in English. This is the second movie that she has directed, her first being Cheerful Caretaker in 2009. Although the movie was set for release in April of this year, some post production difficulties pushed back the date of release to June 24th. Today, YG Entertainment released a trailer for the movie, revealing a bit more about the plotline of the movie. Although titled Magic, a big focus of the movie seems to be about music. No surprise there since�Goo Hye Sun has taken up singing already, even�singing for the movie, �and also had a very small appearance in August Rush, a movie about a child guitar prodigy. You may or may not like the girl, but there is no argument that she is one hard-working entertainer. Check out the trailer below: http://www.youtube.com/watch?v=AoRdUm4FOdA It's been about a year since we've seen her on the screen when her popularity exploded with Boys Over Flowers, but fear not. Goo Hye Sun has also been cast in an untitled musical for 2010.
