Actor Yim Si-wan is known for tackling diverse roles, but his latest challenge as lead in the Netflix thriller "Mantis" pushed his boundaries. The film, a spin-off of the hit Netflix film "Kill Boksoon," features Yim as Han-ul, a top-tier contract killer who fights using dual sickles. To play Han-ul, Yim focused on creating a distinctive, low-class energy, describing the character as needing to be "a bit vulgar, with a rough and showy style." Singer who never quitsDespite his success as an actor, Yim remains firmly committed to his musical career. "That means everything from staying in shape for action roles to studying English, which I see as a 'necessity, not an option' for a global career,” Yim said.
