Overview

ComedyActionScience Fiction

In the Qin Dynasty, time-traveller Hong Siu-lung has lived in seclusion with his family for twenty years. Yet every step he takes remains under the watchful eye of his former disciple, now the Qin Emperor. On the brink of ultimate power after conquering the six warring states, the emperor is suddenly ambushed by a mysterious team wielding advanced weapons clearly originating from Hong’s time. Drawn together by fate again, Hong and Qin Emperor are forced to confront the long-buried conflict between them, because the future now depends on how they settle their past.

Deep Dive

Trivia, insights & behind the scenes

Cultural

Based on the legendary 2001 TVB series 'A Step Into the Past' — this film reunites the original Hong Siu-lung (Louis Koo) after 24 years, essentially fan service as blockbuster.

Trivia

The 'blunt' keyword refers to Hong's signature weapon from the series, a modern police baton he brings to sword fights. The film amplifies this to ridiculous degrees.
