Here's a short subject from MGM released to promote MGM's production of THE UNSINKABLE MOLLY BROWN. In an effort to stand out, it approaches the subject in terms of costuming, under the supervision of Morton Haack. He began work in the movies as an assistant to Miles White, and began to be credited in the late 1950s. By the middle of the 1970s, his name had disappeared from the credits, and he died in 1987 at the age of 62.
MOLLY BROWN was one of the road show productions that the big studios used in the 1960s as 'tentpoles' to their production slate. When they worked, as with, say THE SOUND OF MUSIC, they were wildly successful. When they didn't, as with CLEOPATRA a few years before, they nearly sank their studio.
