Juno Temple in a still from "The Three Musketeers."

Juno Temple (“Maleficent”) has joined Claire Foy (“The Crown”) to star in Steven Soderbergh’s next untitled film. No plot details have been released, but the film seems to be yet another unique project from the creative Soderbergh.

According to Variety, the film has the working title “Unsane” and has been shot on an iPhone à la indie film “Tangerine.” Soderbergh will be directing the film, which promises to be anything but cookie cutter. The director has worked on a plethora of films, including directing the hit “Ocean’s Eleven” trilogy and the off-the-wall 2005 film “Bubble.” The latter was a complete experiment, with Soderbergh casting locals who wrote their own lines and used their own homes as film sets, according to Roger Ebert. The latest film project from Soderbergh comes on the heels of his latest film, “Logan Lucky,” which premieres next month.

Temple is best recognized for her latest work on “Vinyl” and “The Most Hated Woman in America.” She also stars in “Philip K. Dick’s Electric Dreams,” an upcoming Netflix series based on the Philip K. Dick novel. She previously starred in a number of critically acclaimed films, including “The Dark Knight Rises,” “Maleficent” and “Atonement.”

Foy shot to fame last year in Netflix’s “The Crown,” where she played Queen Elizabeth II alongside Matt Smith (“Doctor Who”), who portrayed Philip, Duke of Edinburgh. Foy also portrayed Anne Boleyn in “Wolf Hall” and Amy Dorrit in “Little Dorrit,” among others.

A premiere date has not been announced for the film.
