[1] After writing a few films (Golden Earrings (1947), The Loves of Carmen (1948) and Shockproof (1949) ) for Paramount and Columbia Pictures, she spent the greater part of her career working for Metro-Goldwyn-Mayer.
There, she wrote the screenplays for such films as King Solomon's Mines (1950), Kim (1950), It's a Big Country (1951), Plymouth Adventure (1952), Lili (1953), Flame and the Flesh (1954), The Glass Slipper (1955), I'll Cry Tomorrow (1955), Forever, Darling (1956) and The Unsinkable Molly Brown (1964).
[2] As part of her work for Lili, Deutsch wrote the lyric of the song Hi-Lili, Hi-Lo, which has been a popular bittersweet ballad for cabaret singers ever since.
Shortly after Deutsch's Barnard graduation, she was asked to write something to recite on a radio show to be aired just two days later in honor of the late actress Jane Cowl.
This became Gay's signature tune and remained in EMI and Reader's Digest catalogues (appearing on the Family Favourites box set) for more than 33 years.
