A new clip has been released from next week’s big release, the Claire Foy-led Steven Soderbergh film Unsane. The film follows a young woman who is involuntarily committed to a mental institution where she is confronted by her greatest fear–but is it real or is it a product of her delusion?

We reviewed the film at the recent Berlin Film festival, where it was received rather positively. Audiences will get a chance to see what they think of the horror-thriller – all reportedly shot on an iPhone – when it opens in UK cinemas on March 23rd.
