It has been revealed that actor Cha Seung Won has pulled out of filming in Japan for "Athena: Goddess of War" due to poor health. As a result, Cha's involvement in the drama will now be drastically reduced. Cha had departed with the production team to Japan last weekend for overseas filming, but his health began to deteriorate as the days went by, and it was suspected he had developed symptoms of sepsis from food poisoning. Taewon Entertainment officials decided to send Cha back home to Korea where he is now resting, and they will decide again on his involvement depending on his recovery. With the drama debuting in December, the schedule is already very packed, and there's simply no time to accomodate any re-filming for Cha in Japan. As a result, the screenwriter must modify the script drastically to reduce Cha's involvement in the drama, since he originally had a large part. An official said that they will do their best to minimize the possible impact to the drama. "Athena" will be broadcast through SBS from December 13th.
