The Clock was designed by MGM as a "small" picture--though characteristically, it was a bigger production than most "A" efforts from any other studio. Paul Gallico's simple story involves a girl (Judy Garland) and a GI (Robert Walker), who meet under the huge clock at New York's Pennsylvania Station. Over the next 48 hours, the girl and the soldier fall in love, make the acquaintance of such lovable gotham types as cabbie James Gleason and inebriate Keenan Wynn, and decide to get married before the GI is shipped out again. The enormous Pennsylvania Station set, combined with some unusually convincing back projection (MGM was hitherto notorious for the worst back projection in the business) has convinced even lifelong New Yorkers that The Clock was actually lensed in Manhattan rather than Hollywood. Director Vincente Minnelli injected further visual dynamism in The Clock by seldom repeating the same camera angle twice.
