According to the Hollywood trade publication Tracking Board, Soderbergh shot his latest film, titled Unsane and starring The Crown's Claire Foy and Juno Temple, in secret with an iPhone. Little else is known about the film except that Soderbergh plans to self-distribute it domestically through his Fingerprint Releasing banner, which the director founded in order to test out distribution models for his most recent film, Logan Lucky. Before that, Soderbergh pushed boundaries by shooting Starz' The Girlfriend Experience on high-definition video with mostly non-actors. Since kicking off his career with 1989's seminal indie film sex, lies, and videotape, Soderbergh has consistently been at the vanguard of risk-taking in low-budget filmmaking.
Recently, Soderbergh encouraged aspiring filmmakers to "get a script and start shooting on an iPhone" in a Reddit AMA. We're glad to see he took his own advice.
