Jeon Ji Hyun has cornered the actress market on sassy and doesn’t look to relinquish the crown anytime soon judging from the previews showing her mermaid character giving Lee Min Ho‘s conman attitude in Legend of the Blue Sea. It’s only fitting that screenwriter Park Ji Eun uses this opportunity to reunite Jeon Ji Hyun with her most classic costar Cha Tae Hyun from their hit movie My Sassy Girl. Cha Tae Hyun also worked with Park Ji Eun in Producer so this is a double reunion of sorts, only thing missing if getting Kim Soo Hyun to pop by and spice up the joint. Cha Tae Hyun filmed his cameo this weekend for Legend and the drama releases for premiere November 16th after Incarnation of Jealousy ends this week. There are new mermaid stills out showing Jeon Ji Hyun in and above the water, and it’s probably fantasy that a woman looks as good as she does submerged in salty water.
