The majority of the movie was shot in three locations: The exterior of Garth Manor was shot at the Kimberly Crest Mansion in Redlands, California. The hedge maze was brought in as there was no actual garden maze on the mansion property. The inside of Garth Manor was filmed in a residential home in Pasadena, California. The frat party was filmed in an apartment lobby in Los Angeles, California. The seemingly many tunnels in the movie were actually only two corridors through which the director had the actors repeatedly running from different angles.
