Variety:

Juno Temple is set to co-star with “The Crown’s” Claire Foy in Steven Soderbergh’s next movie, sources tell Variety.

The official title of the pic, which Soderbergh will direct, is currently unknown, but sources says it has a working title of “Unsane.”

Plot details are being kept under wraps, but insiders say Soderbergh shot the entire film on an iPhone, similar to the indie hit “Tangerine.”

Big fan of Soderbergh. His movies include Erin Brockovich, Traffic, and the Oceans 11 series, just to name a few. He does love to experiment.
