Equilibrium Easter Egg - Various Cameos

In the first few minutes of the movie, when the screen is black after Preston kicks down the door and the police shoot out the lights, you can hear two people whispering back and force. One of the voices is the director.

When the police break into Preston's home, and Preston get's a gun up to one of their necks, the officer hurriedly explains that they have a warrant. The voice is that of the director.

In the warehouse scene, when Preston is trying to convince the sense-offenders to escape, the shot cuts to a man being shot by a police guy. The man being shot is the director. The officer shooting him is Christian Bale (Preston)'s stunt double.

Most of the military vehicles in the movie are actually fire fighting vehicles from an airport near where Equilibrium was filmed.
