McFerrin went to California in 1958 to work on the Otto Preminger movie, "Porgy and Bess". The casting plans for this production of the George Gershwin opera slated Sidney Poitier as Porgy. Poitier was to act the role onscreen and lip-synch the musical numbers. McFerrin was engaged to provide Porgy's singing voice. The McFerrins settled in Hollywood that year so that McFerrin could begin working with Sidney Poitier. When the movie was released in 1959, the New York Times stated that, like Poitier's acting, McFerrin's singing was "as sensitive and strong as one could wish." The soundtrack was released as an LP.
