The Sacrament (2013, dir. Ti West)

A documentary crew travels to a remote religious community to conduct an interview. Its found-footage approach to its riff on the Jim Jones/Jamestown cult mass suicide works, but the film doesn’t convince in the storyline logic of its sudden dark turn. A shame, as there’s talent involved, and Gene Jones is great as the messianic Father.

The Standoff at Sparrow Creek (2018, dir. Henry Dunham)

Seven members of a Texas militia meet at their headquarters in the aftermath of a mass shooting. Excellent and absorbing single-location thriller, which wears its touches of Pinter lightly. A hugely impressive debut feature; highly recommended.
