Bud Abbott and Lou Costello explode in their first starring feature (1941), a musical comedy that opens with President Roosevelt signing the peacetime draft bill. As a couple of street-corner tie salesmen who unwittingly enlist in the army, the two unload their treasure chest of polished vaudeville routines, ranging from a contentious, increasingly absurd rifle drill to brain puzzlers and shortchange scams that send Costello into a rage. They’re perfectly complemented by the close-harmonizing Andrews Sisters at their peak, who entertain the troops with “Boogie Woogie Bugle Boy” and “I’ll Be With You in Apple Blossom Time.” Shemp Howard supports Costello in a musical number, and Nat Pendleton (Horse Feathers, The Thin Man) is a fine foil as the platoon’s roaring drill sergeant. Arthur Lubin directed. Reviewed this week in Section 1; 84 min., in 16-millimeter. Also on the program: Michael Audley’s 1945 short The All-Star Bond Rally, with Bob Hope, Bing Crosby, Frank Sinatra, and Harpo Marx. a Sat 7/28, 8 PM, LaSalle Bank Cinema. –J.R. Jones
