The bal-chatri originated in East India as a trap developed and used by falconers to catch suitable birds of prey to train for use in hunting.
This was the king's hunting service, run by the Grand Veneur (the Master of the Hunt and Royal Game Warden), consisted of the vénerie (hunting on horseback), louveterie (the hunt of wolves run by the Grand Louvetier), falcon hunting (run by the Grand Falconer) and the vautrait (boar hunt, run by the Capitaine du vautrait or Capitaine des toiles).
The scenes of the Life of Christ are unusual in Spanish painting at this period; these are in American museums, while smaller elements including scenes of hunting and falconry and decorative copies of textiles are in Madrid as well as New York.
Boyce, an expert in the sport of falconry—thus, the nickname "Falcon"—gets a job at a civilian defense contractor (TRW, called "RTX" in the movie) working in the so-called "Black Vault," a secure communication facility through which flows information on some of the most classified U.S. operations in the world.
