Passage: One of the film's most shocking moments involved an actual, severed, horse's head. Coppola received some criticism for the scene, although the head was obtained from a dog-food company from a horse that was to be killed regardless of the film.  On June 22, the scene where Sonny is killed was shot on a runway at Mitchel Field in Mineola, where three tollbooths were built, along with guard rails, and billboards to set the scene. Sonny's car was a 1941 Lincoln Continental with holes drilled in it to resemble bullet holes.

The house used as the Corleone household and the wedding location was at 110 Longfellow Road in the Todt Hill neighborhood of Staten Island. The wall around the Corleone compound was made from styrofoam. Scenes set in and around the Corleone olive oil business were filmed on Mott Street.After filming had ended on August 7, post-production efforts were focused on trimming the film to a manageable length.

In September, the first rough cut of the film was viewed. Many of the scenes removed from the film were centered around Sonny, which did not advance the plot. By November, Coppola and Ruddy finished the semi-final cut. Debates over personnel involved with the final editing remained even 25 years after the release of the film. The film...
