Actress Kim Min Jung will not be continuing as the leading lady of MBC's Hero opposite Lee Junki due to her prolonged shoulder injury. We reported late last week that Kim Min Jung had been having problems with her right shoulder, having been diagnosed with calcified tendonitis. Her injury had gotten so bad that she couldn't quite move her right arm fully and treatment had been taking longer than expected. With Hero only a week away from it's 11th November premiere, it was becoming increasingly impossible for Kim Min Jung to return to filming in the short term because of the excessive pain. According to the production team, Kim Min Jung had herself submitted a request to leave the production on 31st October because of her injury. The production had been in lengthy meetings for the past two days to find a solution and they finally announced on 2nd November that they will accept Kim Min Jung's decision. With time running out and Kim Min Jung unlikely to return soon, there was no other alternative. A production representative said, "It's going to be a very difficult task in seeking a replacement in the next few days, but we will do our best." With Kim Min Jung out of the picture, all the existing filming and promotional material will no longer be relevant. MBC is definitely going to have to conjure some magic in the next couple of days.
