Harry Cohn monitored the budgets of his films, and the studio got the maximum use out of costly sets, costumes, and props by reusing them in other films. Many of Columbia's low-budget "B" pictures and short subjects have an expensive look, thanks to Columbia's efficient recycling policy. Cohn was reluctant to spend lavish sums on even his most important pictures, and it was not until 1943 that he agreed to use three-strip Technicolor in a live-action feature. (Columbia was the last major studio to employ the expensive color process.) Columbia's first Technicolor feature was the western The Desperadoes , starring Randolph Scott and Glenn Ford . Cohn quickly used Technicolor again for Cover Girl , a Hayworth vehicle that instantly was a smash hit, released in 1944, and for the fanciful biography of Frédéric Chopin , A Song to Remember , with Cornel Wilde , released in 1945. Another biopic, 1946's The Jolson Story with Larry Parks and Evelyn Keyes , was started in black-and-white, but when Cohn saw how well the project was proceeding, he scrapped the footage and insisted on filming in Technicolor.
