As a surprise treat tonight, Shudder just released Jeff Barnaby‘s zombie horror film Blood Quantum on their platform in the US, UK and Ireland.

In Blood Quantum, the dead are coming back to life outside the isolated Mi’gmaq reserve of Red Crow, except for its indigenous inhabitants who are immune to the zombie plague. Amid the chaos, a tribal sheriff must protect his son’s pregnant girlfriend, apocalyptic refugees, and reserve riff-raff from the hordes of walking white corpses.

Shudder recently released a blood-soaked red band trailer for Blood Quantum, which looks like one of the better zombie films in recent years.

Joe Lipsett reviewed the film for us out of the TIFF World Premiere, writing 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.”
