"The Crown" breakout and Emmy nominee Claire Foy is the star of Soderbergh's new low-budget indie experiment.

Steven Soderbergh has shot a movie on an iPhone starring “The Crown” breakout and Emmy nominee Claire Foy and Juno Temple. The news comes just ahead of the release of “Logan Lucky,” Soderbergh’s first feature in four years, which opens in August.

The Tracking Board initially reported the project, with Variety confirming Temple’s participation.

The project’s working title is “Unsane.” Soderbergh is planning to self-distribute the movie in the U.S. through his Fingerprint Releasing, though he is reportedly seeking an international distributor. No plot details have been released at this time.

“Unsane” would be another high-profile feature shot on an iPhone following the success of Sean Baker’s “Tangerine.” Soderbergh has been a champion of low-budget experimental film production, as seen in films like “Bubble” and “The Girlfriend Experience.” The former was shot on high-definition video and starred only non-professional actors from the Ohio region where the movie was filmed.

News of the movie’s existence comes at a formidable time in Soderbergh’s career. Although his Cinemax drama series “The Knick” was recently canceled, he’s got “Logan Lucky” in theaters August 18, plus three television series in various stages of development: Netflix’s “Godless,” HBO’s “Mosaic,” and the second season of Starz’s “The Girlfriend Experience.” He’s also a producer on Warner Brother’s all-female “Ocean’s Eight” reboot.

Foy, meanwhile, is following her breakout year on the small screen with a starring role in Andy Serkis’ directorial debut “Breathe.” Bleecker Street opens the drama, co-starring Andrew Garfield, October 13.

Temple stars opposite Kate Winslet in the upcoming Woody Allen movie “Wonder Wheel.”
