When Jeremy first finds Weldon Parish (Harvey Keitel) in his wine cellar, Parish turns towards him, brings his arm across his chest, and says "Klaatu barada nikto." This phrase originated in the 1951 science-fiction film The Day the Earth Stood Still, when aliens stop the planet Earth and warn its inhabitants that they must cooperate or the planet must be destroyed. The 2008 remake starred Keanu Reeves, who insisted that the line be included. [N.B. if you have subtitles turned on for this film, it is likely that they will read something like "says a foreign language." ]
