Best known to posterity as the third wife of Cary Grant, Betsy Drake enjoyed a substantial film career during the postwar era. In Pretty Baby, Drake plays Patsy Douglas, an enterprising young lady who always assures herself a seat on the subway by carrying a doll wrapped in baby bunting. Through a series of complications that could only happen in a movie, it is eventually assumed that the "baby" is genuine. Patsy's bosses, advertising executives Sam Morley (Dennis Morgan) and Barry Holmes (Zachary Scott), hope to use Patsy's bundle of joy to land an important client, grouchy baby-food tycoon Cyrus Baxter (Edmund Gwenn). Most of the film is a not-so-subtle swipe at radio and TV advertising, considered a rich source of humor back in 1950. Cast in a tiny role as a receptionist is future "June Cleaver" Barbara Billingsley.
