Dir: Steven Soderbergh (15, 90 mins)
Flinging off his alleged retirement, Steven Soderbergh is very much back. After the heist hijinks of Logan Lucky, this is a lo-fi psychological horror that allows Clare Foy to throw off the shackles of The Crown in daring style. Shot entirely on iPhones, it follows Foy’s character as she is involuntarily committed to a mental institution. Foy is attempting to deal with a digital stalker who refuses to leave her alone. She eventually moves to another city in a bid to escape but keeps seeing her stalker everywhere. Is he real, however, or imaginary – a product of a deluded mind? She goes to a facility to explain her worries and ends up being committed. A claustrophobic Hitchcockian horror ensues as she tries to convince everyone she is sane, calling in the police and her mother but to no avail: she should have read the small print on the forms she signed and is now trapped, potentially at the mercy of her stalker or her own imagination. Foy shines whilst Soderbergh has fun with the concept, making a down-and-dirty B-movie thriller.
