Judy Garland puts Gene Kelly (in his MGM screen debut) through his musical paces in this tuneful delight about a couple of vaudeville hoofers on the rise. But things go inconveniently dark when America enters World War I and Kelly gets his draft notice to report for duty. Will he dodge the draft now that stardom is just within reach? Includes the title tune (a great duet for Judy and Gene) and "Ballin' the Jack." Busby Berkeley directs.
