With a stellar cast led by actors Chang Chen and Janine Chang, the upcoming sci-fi thriller The Soul, set to open across domestic theaters on Jan 15, may make up for this disappointment. Actor Chang Chen stars a prosecutor in The Soul. [Photo provided to China Daily] Adapted from sci-fi writer Jiang Bo's award-winning novel Yi Hun You Shu (A Means To Transfer Souls), the story starts with a mysterious murder of a tech company tycoon. As the investigation gets underway, a shocking scheme is unraveled, exposing the complexity of humanity. Memory transplants, one of the most popular themes in sci-fi circles in recent years, are prominently featured in the film.

His pale, gaunt look seen in trailers and still images has sparked much interest among audiences, propelling the film to become one of the most anticipated works this month. Director Cheng says his father's death from cancer gave him a personal connection the film, helping him to reflect on the bonds between the deceased and the living in a more profound way.
