Plot and premise

The story is set in Manchukuo, the Japanese-controlled puppet state in northeastern China, in the 1930s. Four Communist special agents who received training in the Soviet Union, two couples, parachute into the snowy forests and enter Harbin to carry out a secret operation code-named "Utrennya," whose purpose is to find and escort out of the country a witness who can expose Japan's inhuman experiments.¹^•⁶ Zhang Yimou explained in an interview that "Utrennya" means dawn in Russian, and that the story's core is the sacrifice of unnamed heroes.⁷

Because a traitor has betrayed the group, the agents are inside a trap laid by the puppet regime's secret service from the first moment of their landing. To reduce the risk of mutual betrayal, the team splits into two pairs, deliberately separating the couples so that no partner knows the other's movements.⁸ An underground agent embedded in the enemy's secret-service section, Zhou Yi (Yu Hewei), must protect the four while keeping his own cover, and the group ultimately completes the mission and eliminates the traitor.⁴

Narrative approach

An unconventional structure. In a conventional spy thriller the mission itself drives the plot, but Cliff Walkers reveals the betrayal and the leak of the operation at the very beginning. The main narrative becomes the four agents' struggle, aided by the mole Zhou Yi, to evade capture and stay alive, while the actual execution of "Utrennya" is dispatched briefly at the end. Critics described this shift of focus from "rescue" to "survival" as a deliberate break with audience expectations, one that could also leave the mission's resolution feeling abrupt.⁶

The film assembles the standard elements of the Chinese espionage genre, a lineage running from Tian Zi Di Yi Hao (1946) through the post-1949 "anti-special agent" films to the television wave of An Suan, Lurk, and The Message: opposed camps, lone heroes deep in enemy territory, and tests of loyalty and betrayal.⁹ Reviewers noted its visual register of ceaseless snow, cold urban spaces, and blood-red violence, with agents in black coats moving through night streets in a style recalling film noir.⁹ Several commentators observed that the film's genre identity is more visible than Zhang's usual authorial signature, a departure from the visual spectacle of his earlier work such as Hero and Shadow.¹⁰^•¹¹

Production

The screenplay originated with Quan Yongxian, the writer of the 2012 spy television series The Cliff (悬崖); he and Zhang Yimou developed the film script together, with Zhang emphasizing the espionage plotline and the "Utrennya" mission that in early drafts had been reduced to background.⁸^•⁷

Shooting in extreme cold. Production began in December in the Snow Township of Heilongjiang province and ran 159 days, interrupted by two 14-day quarantines of the entire crew during the COVID-19 pandemic, before wrapping on May 19, 2020.¹² The crew filmed in real forests at temperatures around minus 40 degrees Celsius, so that frost-reddened faces and visible breath could not be faked in post-production; Zhang joked that the "breath was the most valuable thing."¹³ The team also built a 1:1 reconstruction of 30,000 square meters of Harbin's Central Street, down to shop windows and ice flowers on glass, to recreate the 1930s city.¹³

The film was produced by China Film Co., Ltd., Emperor Motion Pictures, Shanghai Film Group, and Huaxia Film Distribution, among others.¹⁴

Box office

Cliff Walkers opened in the crowded 2021 May Day holiday period and led the period in audience word of mouth, passing 200 million yuan within 44 hours of release.¹⁰ It lost the holiday-period box office crown to the romance My Love by 8 million yuan but overtook it afterward on the strength of its reputation, and its cumulative total reached 952 million yuan by mid-May, already the highest-grossing Zhang Yimou film since The Great Wall.¹⁵ It passed 1 billion yuan 21 days after release, the second film of Zhang's career to reach that mark, and by the week of June 14 to 20, 2021 its cumulative total of 11.78 hundred million yuan surpassed The Great Wall's 11.73 hundred million yuan, making it his highest-grossing film to that point.³ The Numbers records a worldwide total of US$177,454,106.⁵ It also broke the Chinese record for May Day-period action/suspense films.¹⁶

Overseas, the film ran in Hong Kong cinemas from April 30 to July 29, 2021, grossing HK$3,661,577, and opened in Japan on February 10, 2023.¹⁷^•¹⁸

Reception and awards

On Douban the film holds 7.4 out of 10 from 810,284 users, with about 61 percent of raters giving four or five stars.² On Rotten Tomatoes it holds an 80 percent Tomatometer from 51 reviews and a 72 percent audience score, with the critics' consensus calling it "stylish and exciting."¹ Chinese critics were broadly positive: one widely repeated judgment held that it was the best Chinese spy film since The Message (2009), while others argued that the second half weakened and that the constant snowfall served atmosphere more than plot.⁶^•¹⁹ English-language reviews, including those in the Los Angeles Times and Variety, praised its tension and visual craft while noting that the twisty plot could be hard to follow.²⁰^•²¹

At the 34th Golden Rooster Awards the film was nominated for Best Picture, and Zhang Yi won Best Actor at the 36th Hundred Flowers Awards for his role as Zhang Xianchen; it was also nominated for Outstanding Feature Film at the 19th Huabiao Awards.²
