I recall one allkpop reader stating in the article about the 21 actors to star as the male lead in movie 'Beauty Inside' that it might actually matter more who will play the female lead and love interest, Lee Soo.  That actress was revealed to be none other than the dashing Han Hyo Joo!

The movie 'Beauty Inside', which centers on a male character named Woo Jin who wakes up looking like a completely different person regardless of gender, age, and nationality every day, released a new trailer with Han Hyo Joo as Lee Soo, the woman who loves Woo Jin for who he is rather than how he looks.  

Recall that the other 21 actors are (in order): Kim Dae Myung, Do Ji Han, Bae Sung Woo, Park Shin Hye, Lee Bum Soo, Park Seo Joon, Kim Sang Ho, Chun Woo Hee, Ueno Juri, Lee Jae Joon, Kim Min Jae, Lee Hyun Woo, Cho Dal Hwan, Lee Jin Woo, Hong Da Mi, Seo Kang Jun, Kim Hee Won, Lee Dong Wook, Go Ah Sung, Kim Joo Hyuk,and Yoo Yun Suk.  

The movie will hit theaters in July! Check out the trailer above.
