First trailer for anime version of “Winter Sonata”, based on the (same title) Korean drama which was a big hit across Asia a few years ago.
The animation project was revealed in 2007, but only started gaining some serious notice in March 2008 after the announcement that Korean star Bae Yong-joon is going to voice his own character from the original drama… he shares a few words at the end of the trailer.
Update May 29 - Choi Ji-woo has agreed to join the project.
