The rain was falling heavy in Boston on the day I took a bus over to the set of Paul Feig’s Ghostbusters. The tent for craft services was borderline flooded, the crew working outdoors were covered in black ponchos, and the Ecto-1 that sat outside the former Naval Air Station South Weymouth was draped in a tarp -- though that was probably more for the sake of secrecy than weather protection. But the most noticeable thing on set, despite the skies having opened up and the weather being objectively terrible, was high spirits; everyone I talked with was genuinely thrilled to be working on Ghostbusters, rain, shine, dogs, cats, or mass hysteria. The crew, operating under the code name “Flapjack” for the duration of the production, told me it’s the first movie to be shot at Naval Air Station South Weymouth since the base was decommissioned 1997, but walking into the main building, you’d never know it.
