Relentless Fury (2025) Review: Old-School Gunfights Meet a Deadly Contract

This Relentless Fury review looks at a Mandarin-language action film that wears its '90s influences proudly. Directed by Jimmy Hung Tin-Cheung, it pairs Andy On and Vanness Wu in a story about elite mercenaries and a contract with no exit. It is lean, loud and built around gunfights and stunt work.

Relentless Fury Review: The Story So Far (No Spoilers)

The Relentless Fury plot centres on Shadow, a four-person mercenary unit led by Captain Lin Lang. The team has a spotless reputation: flawless jobs, and no civilian or team casualties. That record is the thing they are proudest of.

Then their broker sends a letter sealed with a bullet. It works as a contract they are not allowed to turn down, and it drags the crew into a deadly game. From there the film sets up a test of trust inside the team and their ability to stay alive.

The film debuted on Chinese streaming platform iQIYI on July 11, 2025, which is the Relentless Fury release date we can confirm. It runs about 88 minutes, so it does not hang around. If you like action movie reviews built on momentum rather than complicated plotting, this is the kind of film in question.

What Works in Relentless Fury

The main draw is the physical action. The trade outlet RADII described the film as a brutal throwback to '90s action cinema, praising its raw stunt work and choreographed gun battles. That fits the premise well, since a team of professional killers needs set pieces that feel dangerous.

• A clear hook: the bullet-sealed letter is a simple, memorable device that gets the story moving fast.

• Short runtime: at around 88 minutes, the film has little room for padding.

• A familiar but sturdy theme: loyalty under pressure gives the action a human question to chew on.

The director, Jimmy Hung Tin-Cheung, appears to favour practical action over digital gloss, and that suits the retro mood the film is going for.

Relentless Fury Cast and Performances

The Relentless Fury cast is led by Andy On as Lin Lang, the captain whose perfect record is on the line. On has long been a fixture of Hong Kong and Chinese action cinema, and the role plays to that physical presence. Vanness Wu stars as Roy, and the pairing of the two is a big part of the film's appeal.

The supporting players round out the team and its orbit:

• Sammy Hung Tin-chiu as Raj

• Zhao Renjie as Da Jian

• Zhao Xixi as Song Ya / Wang Qian

• Cathryn Li as Lucy

I could not find detailed critical write-ups of individual performances, so judge the ensemble by the trailer and your own taste for the genre. Action ensembles like this tend to live or die on chemistry, and the setup gives the actors a strong reason for tension.

Where Relentless Fury Stumbles

Published critical coverage is thin, and audience scores are modest. Simkl shows 5.5 out of 10 from about 100 votes, and TMDB's score is similarly lukewarm, though both samples are small. That suggests a film with a clear appeal to fans of the style rather than broad crossover praise.

The premise is also well-worn. Elite team, mysterious employer, a job that cannot be refused: viewers who have seen similar thrillers may guess the broad shape of the game. Cast members like Zhao Xixi and Cathryn Li may also have less room than the leads, which is common in a film this short.

If you want a layered crime saga, the short running time may feel limiting. Fans of crime movie reviews who want deep plotting may want to adjust expectations.

Is Relentless Fury Worth Watching?

Yes, if you want a compact, gun-heavy throwback and do not need much more. The film seems designed for action fans who enjoy stunt work and choreographed shootouts, and it delivers that in under an hour and a half.

It is not a major event, and the lukewarm audience numbers are a fair warning. But as a streaming watch, the low time investment makes it easy to try.
