Trivia: The film is directed by Kurt Wimmer who also directed Equilibrium. Both films not only use similar battle techniques (gun kata), but William Fichtner also plays a similar role in both movies: Both roles - Garth and Jürgen - are with the underground movement against the totalitarian regime of the movie.
Trivia: All of the guards are either carrying G36C's or SIGSauer 550's, except for one. The guard who tries to shoot Violet after she has taken the case, is carrying a heavily modified AR-15. This was done because neither a G36C or a SIGSauer 550 could be field-stripped in a matter of seconds, unlike the AR-15, the parts of which also make useful weapons, according to this film.
