So I have no idea what happened but there is a change to one of the female actress leads in the K-drama Knock Off. Young actress Kim Shi Eun has dropped out and rookie actress Bang Hyo Rin has been cast in her role. Knock Off has already started filming so it’s a very interesting situation, and most recently happened in a much more high profile way when then rookie actress Park Hae Eun landed the high profile female lead role in the Hong Sisters drama Alchemy of Souls and started filming only to be replaced by Jung So Min after reportedly the production was not pleased with Park Hae Eun’s performance in the early shoots. These things happen so hopefully this is just a small blip for both Kim Shi Eun and the production of Knock Off.
