Goofs

During the shootout on the bridge, Orin Boyd knocks out an enemy and takes from him a submachine gun. Though each following shot shows Boyd wielding a .45 semiautomatic pistol instead of the weapon he just took, the gun still fires in automatic mode, which is impossible for that kind of weapon.

During the happy face helicopter attack sequence on the bridge, trees that are clearly covered in green leaves in some shots are bare in others, and snow is visible along the riverbank in some shots but not in others. This is due to part of the scene being filmed during summer time, and subsequent retakes being shot several months later (see Trivia).

When Boyd is trapped in the black van, a door gets ripped off by a parked car. Moments later the door is back.

When Boyd first confronts the carjackers, the car thief with the pistol can be seen holding the pistol in his belt, with his shirt pulled behind it. However, the next scene shows the thief pulling his shirt up, uncovering the pistol under his shirt

Boyd grabs a submachine gun, a Micro Uzi, which changes to an fully automatic Glock 18 between shots (although the sound remains constant throughout as that of a submachine gun).

In the 1987-1994 Range Rovers of the type that Mulcahy drives, the button that sounds the horn is located on the end of the turn signal lever. However, during the chase scene, Mulcahy's horn sounds when she presses the center of her steering wheel.

While this film was correct in not having front plates on vehicles (Michigan only has rear plates), a government vehicle in the state of Michigan wouldn't even have a place to put a front plate, as all new vehicles sold in the state of Michigan don't even have that feature. Only used, out of state vehicles do.

At the 17:31 mark It's says "Covnty Jail" on the building instead of "County Jail." The historical reason for this is older buildings often use Roman-style architecture, and use the Latin alphabet, which didn't originally have the letter "U." The usage of the letter V instead of U on older buildings is a common occurrence.

On a number of occasions very visible dummies are substituted for real actors.

The police cars on the bridge in the beginning of the movie have neither rear view mirrors nor partitions between the front and rear seats.

The board with which T.K. hits George is obviously foam rubber - it bends when it hits him.

The city is supposed to be Detroit, but during the opening bridge scene, the Calgary Tower (in Canada) can be seen clearly.

Obvious stunt double in the e motorcycle chase.

(at around 14 mins) When Steven Seagal is in the gun fight with the masked bandit in the Medical Center, you can hear the gun clip drop, then you see & hear the gun clip again later.

In the first action scene on the bridge, some of the pistons attached to the bottom of the trucks to make them flip over are visible.

When DMX changes clothes from his street outfit to a suave suit, a crew member's reflection can be seen on the closet door watching him.

Toronto Street Car tracks are occasionally visible.

The movie takes place in Detroit, but when Orin is fighting with Anthony Anderson, the background shows The Bay. The Bay ( The Hudson's Bay Company) is a Canadian store.

Other visible Toronto landmarks early in the movie include the Canadian Broadcasting Corportation (CBC) - the large building with red crosses in the window, and Roy Thompson Hall, the glass domed building.

The entire opening sequence on the bridge has numerous obvious Calgary landmarks, from the Calgary Tower to the very obvious Telus building. Telus is a company that operates primarily in Western Canada, and has absolutely no presence in the US.

Although the film is set in Detroit, there are at least two instances of shots that show that Hamilton, Ontario is standing in for the Motor City. Early in the film, when Boyd and his partner are driving through "Detroit", there is a clearly visible marquee showing the logo of Skydome, a stadium in Toronto. Just as the movie ends, in the street scene where Boyd departs, the bar across the street has a sign with the letters "L.L.B.O.," for Liquor Licensing Board of Ontario, on it. During the chase Tim Horton's is visible, too (this particular store is located at the corner of Hughson and King Street East in Hamilton, Ontario).
