According to ZakZak news, the production of the upcoming anime Winter Sonata has been delaying. Although the first episode will be aired on October 17th, the producers have completed only three episodes. ZakZak reported there should be at least five episodes completed before the airing of an anime.
An anonymous staff disclosed to ZakZak that a change of the director last June and the interference of the main actor Bae Yong Joon in the anime production have been a great burden for the staff.
The production committee of Winter Sonata admitted that they have changed the director and there are only three completed episodes, but denied the delay in the schedule and Bae’s interferences.
