Fall In was the fourth of Hal Roach's 1940s comedies revolving around the misadventures of Doubleday, an army recruit blessed--or cursed--with a photographic memory. This time, Doubleday (
William Tracy) and his pal Sgt. Ames (
Joe Sawyer) crash a fancy fund-raising dinner. They redeem themselves by capturing a Nazi spy, who poses as a super-patriot named Arnold Benedict (!) A zany sequence at a gambling table and a wild climactic free-for-all highlight this above-average entry. A Hal Roach "Streamliner" designed for the lower half of double bills, Fall In clocked in at a swift 48 minutes. ~ Hal Erickson, All Movie Guide
