 The scenes showing Father Karras in his room at Georgetown were  filmed in Fordham Universitys freshman residence, Hughes Hall,  fourth floor. Hughes was once the site of Fordham Preparatory  school. Since there was no elevator at the time, the windows had to  be removed in order to accommodate for the camera on a crane. Each  year, Father William OMalley talks about his experience with the  movie after students watch it on the same floor where it was filmed.
