Character mistake: When Troy is getting the bomb ready, the screen shows it will blow in 216 hours, which is 9 days. Yet the agent tells Archer it will blow in 6 days.

Starring: Nicolas Cage, John Travolta, Joan Allen, Alessandro Nivola, Gina Gershon
Visible crew/equipment: At the L.A. Convention Center, just before Castor Troy (as Sean Archer) disarms the bomb, there are a few shots of all the extras evacuating the area. In the interior shot, that looks out through the glass doors onto the street, the tracking crane arm with a seated camera operator and camera on its platform is visible as it shoots an exterior crane shot of all the extras, which was seen among the previous shots.
Castor Troy: You'll be seeing a lot of changes around here. Papa's got a brand new bag.
Trivia: John Woo fought to keep the slash in the title, so moviegoers wouldn't think it was a film about hockey.
More questions & answers from Face/Off
Chosen answer: Although they were on the same side, Troy is currently posing as Archer, which means he would have to do everything that the FBI would expect Archer to be doing. The whole point of the raid was to take out Archer, as well as Troy's gang. He would have rather risked killing part of his own gang than risk exposing his identity to anyone else.
Casual Person
That doesn't really make sense. In the scene, he goes out of his way to shoot him and smiles while doing so, carefully and slowly. Was not a collateral damage situation. The question is why he deliberately goes out of his way to kill him.
