Actress Han Hyo Joo has been cast as the heroine for the melodrama movie, "Only You". A representative of HB Entertainment revealed, "On the 8th, after discussions with our investor, Showbox, we've decided to go with Han Hyo Joo as the heroine. Her pure and innocent charm, as well as her sharp acting skills led to our decision." For her third movie, after "My Boss, My Teacher" and "Heaven's Postman", Han Hyo Joo has been upgraded to the lead role, and she will be acting alongside actor So Ji Sub. "Only You" is a heartwarming story about a love shared between an ex-boxer and a girl who is losing her sight. All for this one girl, the man throws away his destiny. The male character, who draws on both sacrifice and love, became a much discussed topic among the actors. At one time, actor Ryu Seung Bum was cast for the male lead, but he was replaced by So Ji Sub when the production company changed. Also, it was revealed that Moon Bo Mi -  a representative of the production company - directly gave the movie script to Ha Jiwon, Moon Geun Young, Park Bo Young, Han Hyo Joo, and others. The budget for "Only You" is said to be 25 billion won ($22.3 million) and there's been much interest for this movie because it will be Director Song Il Gon's first commercial film. He has already shown his talent for visual aesthetics through 'Flower Island'(2001), 'Spider Forest' (2004), 'Wizards' (2006), 'Dance of Time' (2009) and more. Because of So Ji Sub's busy schedule, they plan to start shooting the movie in March and continue until June. Source: Newsen via Hanafos
