Musical star Ann Miller plays a Broadway leading lady coaxed into reteaming with Larry Parks, her former producer. Parks is now a lowly Army G.I., anxious to produce a show for the troops--with a 200 dollar budget! This being a wartime musical, Ann Miller succumbs to Patriotism and stars in Parks' threadbare production. This being a Hollywood film, the "inexpensive" revue cost several times as much as any real-life show of this nature. Hey Rookie proved a boon to the Columbia publicity department when Ann Miller set a tap-dance record of 550 taps per minute in her climactic musical number. ~ Hal Erickson, Rovi
