If this beauty had accepted the role of Jang Man Wol before IU, the drama would probably have had to replace the entire main cast.
IU is a singer-turned actress who used to come under controversy over her acting skills. It was not until the release of Hotel Del Luna that IU‘s acting was acknowledged by the majority of the audience. Jang Man Wol seems to be born to be played by IU when it brings both her visual and acting to a new level, not to mention her amazing chemistry with the rest of the cast.
Although IU perfectly suits the character, perhaps the audience did not expect that she was not the first choice for the role of Jang Man Wol. The producer of Hotel Del Luna initially offered the part to A-list star Jeon Ji Hyun, but she rejected. The reason for her decision is not disclosed. Before Hotel Del Luna was broadcast, this information caused much regret. Many netizens think that since Man Wol is an attractive and fashionable woman with an unpredictable and eccentric personality, Jeon Ji Hyun seems to be a perfect choice for this character.
However, after the drama aired, it’s hard to see that there is anyone who could portray Jang Man Wol better than IU. Not to mention, if Jeon Ji Hyun had accepted the role, the male lead and the second male lead would probably have had to be replaced by older and more mature actors. Otherwise, the age difference would be too big.
