Attack of the Vegan Zombies! (2010)

Joe and his wife Dionne have had yet another bad crop for their winery. Faced with the prospect of losing the family farm, Dionne convinces her mother (a witch) to cast a spell upon next year's crop. The crop is such a success that Joe hires some college students to help them harvest. However, when a nosy neighbor begins poking around in the fields, he finds out more than he bargained for. Now the question isn't how to best harvest the crop, it's how to keep from being harvested!

Unfortunately the movie Attack of the Vegan Zombies! is not yet available on HBO Max.
