"Unsane,' looks to be a psychological thriller by noted director Steven Soderbergh (Traffic, Sex, Lies and Videotape), which was shot on iPhones. Focusing on the trauma and effects of cyber stalking, the movie looks quite intense and while the iPhone may not hace the visual quality of standalone video cameras, it does manage to portray some of the more unnerving scenes to great effect. 'Unsane," comes to theatres on March 23.
