Another Best Actress winner: In 1950, Judy Holliday reprised for film her triumphant Broadway role as Billie Dawn, the former Brooklyn showgirl turned mistress of a junk-dealer mobster named Harry Brock, played by Broderick Crawford. In this Garson Kanin comedy, the gangster has put hidden millions in his mistress’ name, and suddenly has to marry her to protect his cash. So he decides on forcing her to take a Pygmalion-style crash course in refinement, with William Holden as the guy hired to polish her edges. And what edges. George Cukor directs, and Holliday is a hoot.
