The overseas promotional poster of upcoming crime film "Assassination," starring actress Jun Ji-hyun, has been unveiled.

The film stars Jun -- also known as Gianna Jun -- in the lead role alongside male actors Ha Jung-woo and Lee Jung-jae as coconspirators and partners in crime.

"Assassination" is set against 1930s Shanghai and Seoul, which was under Japanese colonial rule from 1907 until the end of World War II.

Jun plays freedom fighter and nationalist sniper An Ok-yoon in a change of roles from her more lively and sensual choices in the past.

Jun is dressed in a notably conservative outfit, presenting an austere image while holding a rifle, in the Western-style film poster revealed earlier this week.

Her costar Lee plays gang leader and Korean provisional government agent Yeom Seok-jin, while actor Ha plays contract killer Hawaii Pistol.

Director Choi Dong-hun previously worked alongside Jun, a popular actress and celebrated Korean beauty, in the 2012 crime blockbuster "The Thieves," which he both directed and cowrote.

"Assassination," which is in the second half of production, is set for release in Korea this summer.
