"A Star Is Born" (1954)
The greatest of all movie-Oscar moments consists of three words, all but trumpeted by Judy Garland as she clutches her statuette: "Mrs. . . . Norman . . . Maine!" James Mason's performance, as Mr. Norman Maine, is pretty good, too. Ditto Garland's rendition of "The Man that Got Away."
