For the beheading of Judge Curwin, director Philippe Mora shot a cutaway of the judge's bow-tie flipping into the toilet and the bowl being spurted with blood, but the MPAA found this footage more appalling than the decapitation itself, so the shot was removed.
Paul Clemens (Michael) has described the scene in the kitchen with Logan Ramsey (Edwin) as the most difficult scene to film in his entire career. Ramsey kept going off script and Clemens found it practically impossible not to laugh at his various ad-libs.
During the scene in the kitchen when Michael is telling Amanda to leave, a shotgun keeps appearing and disappearing behind them leaning in front of the window.
