Plot hole: Since when do highly trained, professional police/SWAT operatives run lemming-like at perpetrators in an armoured assault vehicle with an M-60 in it? This wouldn't happen.
Ballistic: Ecks vs. Sever (2002)
2 plot holes - chronological order
Directed by: Wych Kaosayananda
Starring: Antonio Banderas, Lucy Liu, Gregg Henry, Ray Park, Talisa Soto
Other mistake: In the scene where Ecks is chasing Sever, you see Ecks put a shell into an open chambered shotgun. This means that there is only one shell in the gun. A moment later when he yells stop inside the building he cocks the gun again. Thus, he is holding up Sever without any shells in the gun.
Robert Gant: There are no innocent people in this world Sever, you know that. Only killers and victims.
Trivia: A video-game adaptation for the Nintendo Game Boy Advance was being made alongside the film. However, the movie was held up in production, and the game ended up being released a year before the movie. It was also based on an earlier draft of the script and was thus quite different plot-wise. A "sequel" game following the movie much more closely was subsequently released after the movie. The games were notable for being first-person shooters that pushed the GBA's hardware to its limits.
