Sam Thompson’s review published on Letterboxd:
Although I don't ever see myself ever returning to Nocturne, it's definitely a competent psychological thriller in the vein of something like Black Swan. The main takeway is that Sydney Sweeney is a very talented actress as she carries this film. Zu Quirke does a great job with the direction, especially with it being her debut feature. Despite being uneven, Nocturne is a decent slowburn into competitive madness that finishes with an ending that worked for me.
Worth a one time watch for sure.
