Claire Foy May or May Not Be "Unsane" in This Gripping New Thriller

Now that Claire Foy is officially leaving Netflix's royal masterpiece The Crown, it's exciting to see what she'll do next. Luckily, we don't have to wait long at all to find out. Following the news that she would play Lisbeth Salander in the film adaptation of The Girl in the Spider's Web and play Neil Armstrong's wife Janet Shearon in First Man, the trailer for a new film called Unsane has dropped.

Starring Foy, it follows a pretty dark and twisty story: "A young woman 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?" What's even crazier is that the film, directed by Steven Soderbergh, was filmed entirely on an iPhone! Damn. This for sure is a far cry from the royal family. Unsane hits theaters on March 23.
