Oscar-winning director Steven Soderbergh’s latest movie ‘Unsane’ was shot entirely on iPhones. The horror thriller stars ‘The Crown’ actress Claire Foy as a woman involuntarily committed to a mental institution and forced to confront her greatest fear. Soderbergh says, “Anybody going to see this movie who has no idea of the backstory to the production will have no idea this was shot on the phone.” ‘Unsane’ hits theatres on March 23, 2018.
