Is There a Niu Lai Trailer?

Niu Lai was made by a two-person team — director Xin Yumeng and his mother, writer-composer Sun Lifang — over more than five years on a budget of only a few thousand yuan. There was no studio, no distributor push, and no marketing budget. The entire promotional footprint at launch was a single poster. No teaser, no trailer, no press junket.

That vacuum is exactly why the film was invisible for its first nine days, and why the internet — not a marketing department — is what eventually carried it. In a very real sense, the “trailer” for Niu Lai turned out to be the mocking clips that strangers posted online.

The footage that went viral consists of short excerpts from the film itself— the crude 3D scenes with characters clipping through one another and stuttering motion that earned the “worse than AI” label. These clips were shared on social platforms as reactions and jokes, not as an authorised trailer.

As of 18 August 2026, the only official way to watch Niu Lai in full is in mainland Chinese cinemas, where it is still screening (showtimes fluctuate sharply with demand). There is no official Western streaming release — not on Netflix, Disney+, or Prime Video — and no official English-subtitled version. If and when an official stream appears, we’ll point to it directly.

In the meantime, if you want the story without the search, our plot explainer walks through the film in plain English, and Why It Went Viral explains why a trailer-less flop became a phenomenon.

Most films are discovered through their trailer: you see the ad, then decide whether to watch. Niu Lai inverted that. Because it launched with no trailer and no press — just one poster — nobody discovered it the normal way. People met the film through mocking clips of its crude animation, then went looking, after the fact, for the trailer they assumed must exist. It doesn’t. The “worse than AI” excerpts effectively became the film’s marketing, produced by strangers rather than a studio.

There’s something fitting about that. A movie whose entire appeal turned out to be its hand-made, unpolished humanity was never going to be sold by a slick trailer. Its promotion, like its animation, ended up being improvised and human — right down to the cinema staff who drew their own posters by hand when demand spiked. If you came here hunting for a trailer, the honest answer is that the phenomenon itself is the trailer.
