Alex Ross Perry’s Queen of Earth looks like a friendly reunion gone seriously wrong. Elisabeth Moss plays Catherine, who retreats to an idyllic lake house with her childhood friend (Katherine Waterston). Unfortunately, when they should have been catching up and splashing around in the water, it looks like at least one of the women—Catherine—starts to come unhinged. This first trailer gives us a rough idea of what to expect from Moss’ performance: ranting, cursing, and some severely creepy facial expressions. The film will be released in select theaters beginning Aug. 26.
