Kim Bum Is Lean, Mean And Ready For Revenge In "Hidden Identity"

Kim Bum will show viewers a different side of himself in his new tVN drama, "Hidden Identity." He plays a former SWAT and SEAL member who joined an undercover investigative team. His character is lean, mean and ready to exact revenge.

Not all of Kim Bum's previous roles have been as sweet as his "Boys Over Flowers" or "The Woman Who Still Wants To Marry" roles but his character in this drama has a violent streak and some anger management issues.

Kim plays Cha Gun Woo, a man bent on revenging the death of his girlfriend. He is so eager for revenge that he may forget which side of the law he is supposed to be on. His nickname is Mad Dog, if that is any indication.

Cha Gun Woo is a member of crime fighting team Number 5, led by Jang Moo Won. Park Sung Woong, last seen in "Fatal Encounter," plays team leader Jang. Also on the team are Jang Min Joo, played by Yoon So Ri, last seen in "Iris 2," and Lee Won Jong, who appeared in "Empress Ki" and "Secret Door." Lee plays Choi Tae Pyeong. Between them the undercover team has mad martial arts skills, expertise in psychology and plenty of useful connections. They are also experts at working around the finer points of the law. What they don't have going for them is a way to control Cha Gun Woo's temper.

But as bad tempered as he is, he must have some positive points.

Kim's agency, King Kong Entertainment, said that the actor took the role because the character appealed to him.

"I found the character named Gun Woo interesting and charming," said Kim in a statement released by his agency.

Kim Jung Min, who worked on OCN's "Bad Guys," will direct the drama. "Bad Guys" was the OCN drama with the highest viewership in 2014.

The Monday-Tuesday drama begins on June 16.

At a press conference for the drama Kim Bum explained his drastic weight loss for the role, saying that he wanted to match his appearance to his character. Altogether he lost 30 pounds and his face became more angular.

He also lost a considerable amount of weight when preparing to play an angel in the melodrama "Padam Padam: The Sound of His and Her Heartbeats." But that character was more tortured than furious.

Kim's most recent k-drama role was in "Goddess of Fire: Jeonji." Since then the 25-year-old actor appeared in the Chinese drama "The Micro Era of Love." Check out the trailer for his new drama below.
