Trivia: John Woo fought to keep the slash in the title, so moviegoers wouldn't think it was a film about hockey.
Trivia: One of John Woo's directing styles is to mark large action sequences with doves. You can see this in Mission: Impossible 2, on the island just before the final action sequence and in the church after the funeral in Face/Off.
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.
Trivia: The magnetic boots worn by all the inmates in the sea prison are the same boots worn by the Goombas in "Super Mario Bros."
Trivia: As an example to the contrast of their characters, Sean Archer's blood type is said to be Type O and Castor Troy's is said to be AB. Type O is the universal donor type and Type AB is the universal recipient type.
Chosen answer: Surgical scar removal is a real thing, usually involving skin grafts or lasers. Keloid scarring is a result of the body aggressively attempting to heal/repair itself after trauma or injury (in this case, the gunshot). With proper surgical techniques, the body isn't traumatized to the point that deep scarring occurs. Of course, just like with the face surgery, the movie exaggerates the results of the scar removal.

I thought he kept it.
He says he wanted to keep it at the beginning of the movie, but when he is about to have his face changed back at the end of the movie, he says he doesn't need it anymore.
