On June 17, 1928, FBO's "The Perfect Crime", directed by Bert Glennon and starring Clive Brook and Irene Rich, debuted. It was the first feature-length "talkie" to appear from a studio other than Warner Bros. since the epochal premiere of Warners' "The Jazz Singer" eight months before. "The Perfect Crime", which went into general release on August 4, had been shot silently. Using the RCA Photophone sound-on-film system, the dialogue was dubbed in afterward—a process then known as "synthetic sound." On August 22, Kennedy signed a contract with RCA for live Photophone recording; more importantly, he also tendered the company an option to buy his governing share of FBO. Two months later, RCA had acquired controlling stock interests in both the studio and KAO.
