I've seen that film before, but wonder how many P-47's were actually assembled that way in theatre. By the time P-47's arrived in Europe, we had a pretty substantial presence (technicians and infrastructure) there, and that's where the majority of them went. People with cranes and other heavy lift equipment don't typically rely on brute force and human labor to assemble airplanes. OTOH, I guess it is possible that a few were hand assembled in the PTO, but most aircraft in the PTO were assembled in the US and ferried via carrier, or were assembled in a developed area (Australia, for instance) and ferried to the combat zone.
