Joo starred in the 2004 film A Family alongside Soo Ae, portraying a single father who has a troubled relationship with his daughter. His performance found favour with critics, with Darcy Paquet of Koreanfilm.org saying, "in his accomplished handling of small details and the film's quieter moments, Joo succeeds in making the father a real person instead of a stereotype",^[3] and in October 2005 won the award for Best Actor at the 50th Asia Pacific Film Festival.^[1]

In 2006 Joo starred in the musical comedy film The Fox Family, learning to sing and dance during a month-long period of intensive training. He chose the film because the story was fun and unconventional, and said, "it was fun to challenge myself and I don't have any regrets".^[2]
