Shudder Sets a Perfect October Date for Post-Apocalyptic ‘Hallowarrior’Shudder is bringing some serious Halloween energy this October, announcing that the post-apocalyptic indie horror film Hallowarrior will land on the service that month. Here’s the plot crunch: “Pumpkin (Milly Shapiro), a Halloween-obsessed post-apocalypse survivor, thinks she’s the last person alive. “The movie is dripping with nostalgic fall atmosphere, cheer-inducing kills, and a lovable ‘final girl’ played by the brilliant Milly Shapiro. I can’t wait for this movie to enter horror fans’ annual October viewing rotation for years to come.” Trick or treat with Hallowarrior when it arrives on Shudder October 16th.
