 The interior of Mrs. Mingotts house was filmed at Rensselaer  Polytechnic Institutes Pi Kappa Phi fraternity house in downtown  Troy, NY, home to about 35 men at the time. Setup and filming took  approximately three weeks and was done while school was still in  session. The first floor was the only one used for filming and  during shoots members of the house had to remain silent upstairs or  leave the house. The shot of the house as a solitary structure on a  small hill is movie magic, as the house is surrounded on both sides  by other buildings.
