The final act dips a bit too deeply into self-referential metaphor, but the first hour or so is a cracking thriller from Takal, who previously wrung horror out of uncomfortable male attention in Green and here mines a collapsed friendship between two women. At first one's sympathies lie more with Anna, the struggling actor who must watch on jealously as Beth gets consistent work and fans but has the gall to be flippant about the quality of her paid gigs. Gradually, however, Mackenzie Davis' cutting performance turns Anna into such a corrupted, bitter individual that you're left feeling more sorry for Beth. About that time, the tension starts to get unbearable, and a scene of Beth's terrified phone call home as the camera pans slowly back and forth is excruciating in its suspense. A compelling riff on the reverberating impact of envy that ripples outward from the precious few roles given to women in the industry.
