Trivia: John Woo fought to keep the slash in the title, so moviegoers wouldn't think it was a film about hockey.
Trivia: The prison that Pollux is in is called Erehwon which is "no where" backwards.
Trivia: One contributor was stationed at George AFB near Victorville, CA where the airport scenes were filmed. The base closed in '92. Here's something if you really want to get technical - they fight inside a hangar and then to the hush house (engine testing area where Cage is blown into the wall by the engine afterburner). It looked as though they went through the hangar straight to the hush house. He worked in both of these buildings and had to either drive to the hush house or walk very far across the flight line. Looks good in the movie, unless you were there...
Trivia: The names Castor and Pollux Troy are taken from the constellation Gemini. In Roman mythology the Gemini which is Latin for "twins", Castor and Pollux, are the twin sons of Leda and the brothers of Helen of Troy and Clytemnestra. According to the myth the twins had the same mother, but different fathers. While Pollux was immortal, Castor was mortal. When Castor died, Pollux asked Zeus to keep them together and so they were transformed into the Gemini constellation.
