Continuity mistake: In the railway station where 47 is being followed by the FSB, Interpol and the older agent, you see the older agent running down the ramp to platform 9 after 47. His jacket is flying up in the back, and there is no weapon visible. When he stops running, he reaches behind him into the waistband and produces a handgun with a silencer.
Trivia: When 47 crashes through the hotel window and the kids turn around, you can see that they're playing a videogame. The game is "Hitman: Blood Money", the first mission to be exact.
Agent 47: The man you've been chasing is a killer. A Ghost. Rumor has it that he works for a group known only as "The Organization." So secret, no-one knows it exists. Takes no sides - yet it has ties to every government. Its sole purpose is the training and conditioning of professional killers. These men are selected at birth - rejects, orphans - all of them - unwanted and disposable. They are made experts in every aspect of combat. And programmed for one purpose... To Kill.
Question: This is perhaps a silly question, but do any Special Forces unit in the world have a uniform like the Russians did in this film (specifically those who tried to storm 47's hotel room near the beginning)? I'm assuming it was designed for the sake of the movie (red eyes, etc) rather than real world accuracy, but I'm interested all the same.
