Keep 'em Flying (1941)

Synopsis
Having joined the army in Buck Privates and the navy in In the Navy, Bud Abbott and Lou Costello signed up with Air Force in Keep 'Em Flying. Abbott and Costello play Blackie and Heathcliff, carnival workers who are fired from their jobs along with their pal, reckless stunt pilot Jinx Roberts (Dick Foran). When Jinx joins the Army Air Corps-the better to be nearer pretty USO singer Linda Joyce (Carol Bruce)-Blackie and Heathcliff loyally join up as well, obtaining low-echelon ground crew jobs. While Jinx tries to cure Linda's brother Jim (Charles Lang) of his fear of flying, Heathcliff pursues a romance with wisecracking waitress Gloria Phelps (Martha Raye), never quite catching on that Gloria has an identitical-twin sister (also Martha Raye). A bit too plot-heavy for its own good, Keep 'Em Flying is at its best when concentrating on Abbott & Costello, who in addition to performing their patented cross-talk routines participate in a zany runaway-torpedo chase and a gratuitous but amusing episode in a spooky carnival funhouse. As a bonus, Costello gets to do a bit of "straight" acting, and he's quite good at it. Deleted scenes include a comedy magic act (later restaged in Abbott & Costello's Lost in a Harem) and a wild episode at a skating rink (reworked two years later in Hit the Ice). ~ Hal Erickson, All Movie Guide
