 While not unique to Jitterbugs, but common to all their WWII  offerings, wartime rationing had an impact on the duos films. In  this case, shoes were rationed to three pairs a year, and the  dancers had to rehearse in bare feet. And because so many young men  had joined the armed forces, the original plan to have 150 jitterbug  teams in the jitterbug scene, had to be reduced, and the fifty  couples planned were reduced to thirty. Not only that, but the "zoot  suits" the duo wore needed a special dispensation because it was at  the time considered a profligate use of material.
