Blood Quantum is a 2019 Canadian horror film written, directed, and edited by Jeff Barnaby and starring Michael Greyeyes, Elle-Máijá Tailfeathers, Forrest Goodluck, Kiowa Gordon, Brandon Oakes, Olivia Scriven, Kawennáhere Devery Jacobs, and Gary Farmer.

[3] Blood Quantum premiered at the 2019 Toronto International Film Festival, where it was named second runner-up for the People's Choice Award: Midnight Madness.

[6] In 1981, on the Red Crow Indian Reservation in Quebec, Canada, fisherman Gisigu catches a number of salmon, and observes that they continue to move after being gutted.

Lysol has become increasingly aggressive towards Joseph and others' tendency to bring outsiders—such as a man and his young daughter, the latter of whom was bitten by an infected person, as well as a girl named Lilith, who hides the fact that she has also been infected—to the compound.

[10] An underlying theme evident from beginning to end in Blood Quantum is that of generational trauma and the historical tension that exists between white and Native individuals.

[11] Indigenous peoples roamed "North America" thousands of years before white colonizers showed up, and debate over the rightful owners of the land have never been settled.

The concept of Natives being immune to the virus and non-natives being susceptible to getting infected is a subtle way of questioning who the rightful owners of Canadian land are, another theme present in the film.

The website's critics consensus reads: "Blood Quantum blends bloody horror with sociopolitical subtext, taking a fresh bite out of the crowded zombie genre in the bargain.

[24] Elisabeth Vincentelli of The New York Times gave the film a mostly positive review, writing that its "central premise is inspired: When dead people come back to ersatz life, it turns out that Indigenous folks are immune — a sardonic twist on their ancestors succumbing to diseases imported by the European settlers.

"[26] Joe Lipsett of Bloody Disgusting wrote that "Blood Quantum serves both as a reasonably entertaining zombie film, but more importantly, as a vital socio-political critique of real historical events in Canada.

"[27] Shea Vassar, a Cherokee Nation staff writer of Film Daze, wrote that "Barnaby is ushering in a new era of Indigenous filmmaking.

While still addressing some of the post-colonial pain that exists within communities today, Blood Quantum is a refreshing break from the same sad drama that is usually regurgitated when filmmakers, even those from an Indigenous or Native background, attempt to talk about the Indian experience.

"[28] The Guardian's Benjamin Lee gave the film three out of five stars, writing that it is "best taken as a violent slab of late-night exploitation, made notable by a powerful conceit and some evocative visuals.

"[29] Brian Tallerico of RogerEbert.com gave the film two-and-a-half out of four stars, commending its action and social commentary but criticizing its "poor performances and awkward dialogue".

[30] David Ehrlich of IndieWire gave the film a grade of "C+", writing: "The filmmaking in Blood Quantum is seldom as compelling as its premise, and it's frustrating to watch such a fresh take on the zombie genre be mired in several of its most rotten tropes.
