Early Firefly promotional images were taken at the Ennis House, a residential dwelling in Los Angeles, designed by Frank Lloyd Wright in the twenties.
The design is based on ancient Mayan temples. Its prominent detail is the relief ornamentation on its textile blocks, inspired by the symmetrical reliefs of Mayan buildings.
Find below the promo shots with the Firefly cast taken at the Ennis house:
The building's exotic design made it an appealing location for Hollywood filmmakers.
Although used as a shooting location as early as 1933 (Female), the house first acquired morbid fame providing the exterior facade for the" House on Haunted Hill", a 1959 B movie starring Vincent Price (see photo below). The 1975 film The Day of the Locust made extensive use of the house as a private residence, but it was in 1982's "Blade Runner" that the house gained a popularity of its own among moviegoers (see photos below). Its exterior also appears as "The Mansion" occupied by Angelus, Spike, and Drusilla in Joss Whedon's television series "Buffy the Vampire Slayer".
