Best comedy movie mistakes of 1942
Factual error: This relates to the first movie with this title, the one with Jack Benny in it. About midway in the film there is a scene with Polish pilots in the RAF in a room. It cuts to a brief shot of airplanes flying which obviously purports to show the Polish pilots flying their airplanes. But, the airplanes shown are circa 1935 U. S. Army Air Corps Consolidated two place fighters, never used by the RAF and in fact totally obsolete and never used by any air force during WWII.
Continuity mistake: When Spencer Tracy takes Katharine Hepburn to the baseball game (about 20 minutes into the film), several plays supposedly from that game are shown. Some of the plays take place on a diamond that has a well manicured dirt path from the pitchers mound to home plate, while others take place on a diamond with an all grass infield and no path.
