Their fourth starring vehicle of 1941, "Keep 'Em Flying" shows the wear and tear of the duo's busy year. The films production values are more skimpy; evidently by filming on location at Cal-Aero in Ontario, California, the producers felt they could cut costs. This doesn't help A&C's flying sequences with their poor rear projection or the rescue sequence at the end, with all-too-obvious miniatures. The real flying stunt sequences sandwiched around them, however, are done well.

What saves the film are A&C's performances and the interplay between Costello and Martha Raye, who plays twins in the film. There are some truly funny moments, but not enough to elevate the film among their best. 6 out of 10.
