A Time-Travel Mission That Could Change History
The story centres on Hong Siu-lung, a Hong Kong police officer who became stranded in the Qin Dynasty following a failed time-travel experiment.
Two decades later, Hong has built a quiet life and remained out of the spotlight. That peace is shattered when a former associate arrives from his own era with advanced technology and a plan to take control of the Qin throne.
The situation becomes even more complicated when the Qin Emperor, once connected to Hong’s past, is attacked by a mysterious force equipped with weapons that clearly don’t belong in ancient China.
Hong is pulled out of hiding and forced to confront unfinished business from his past while protecting the Emperor. Their long-standing conflict now has consequences that extend far beyond their own lives, with the future itself hanging in the balance.
Louis Koo Leads an All-Star Cast
BACK TO THE PAST stars Louis Koo, who leads the film as Hong Siu-lung.
Joining him is Raymond Lam, along with Jessica Hester Hsuan, Sonija Kwok, and Lai-Ming Tang.
The cast brings together some familiar names from Hong Kong cinema, while the film’s martial arts sequences add another major component to the time-travel story.
Sammo Hung Brings the Action
For martial arts fans, one of the major attractions is the involvement of Sammo Hung, who handles the film’s action choreography.
The movie is co-directed by Jack Lai and Ng Yuen-Fai, with Lily He credited as writer.
The result combines classic kung fu action with the science-fiction element of time travel, creating a story where ancient warriors and futuristic technology collide.
