The film's production and distribution company CJ Entertainment said in a recent press release that actress Jeon Ji-hyun and Hwang Jung-min will star in 'He Once Was a Superman.'
The film, slated to open in the first half of 2008, is the comic and heartwarming story of an eccentric who believes that he is a super hero.
Jeon will take on the role of Song Su-jeong, a documentary producer who will resort to all lengths, even manipulation, to create a program that will move the hearts of TV viewers. In the film, she uses "Superman" to make a human documentary.
The actress recently finished shooting a film entitled "Blood: The Last Vampire" based on a Japanese animation.
