Just imagine: one day, a cute child comes up to you, and calls you 'Daddy'. But you've never seen him before.

In the upcoming comedy Making Family, this stunning moment occurs when a South Korean child surprisingly appears in front of his biological father, a Chinese man who donated his sperm nine years ago in the United States.

But just like every tale with a happy ending, the father and child develop to a real relationship after a string of misunderstandings.

The Sino-South Korean production, starring Chinese Canadian actor Aarif Lee and South Korean actress Kim Ha-neul, will premier across the country on Nov 4.

The celebrity-studded cast also includes Mason Moon Moorhouse, the 9-year-old child actor born to a South Korean mother and a Canadian father and award-winning actress Lv Zhong.

Lee, who plays the father, says it's a heart-warming story with a humorous tone.

In the movie, the cultural clash and language barriers are used as funny twists to develop the dramatic storyline, said the film's producers.

Lee, 29 and single, also revealed that the film made him seriously consider getting married and having a child.
