I loved the folk horror elements of 28 Years Later, and this new nightmarish medieval movie follows in its footsteps in all the right ways

Caleb Landry Jones as Walter in Harvest.

Harvest isn't a traditional folk horror movie, but it brings shades of rural dread to Greek filmmaker Athina Rachel Tsangari's latest feature.

Tsangari is no stranger to the weird and wonderful. She's worked as a producer on several of Yorgos Lanthimos' movies – including family psychodrama Dogtooth – and co-wrote her last feature, 2015's Chevalier, with Lanthimos' frequent collaborator Efthymis Filippou.
