Other mistake: Tough beat cop Farley Wood in his spare time built a special electronic machine to feed his cat. He needs to take off for Miami at 3 PM. When his cat is eating before his departure though, the clock on the machine says it's "12 AM", which would be midnight, not noon.
Other mistake: When the coroner lifts the sheet to show the cops Jimmy Kong's body and shows them the dim mak bruise on his chest, you can see Jimmy breathing.
Continuity mistake: A helicopter drops two harnesses down to Chuck Norris (Major McCoy) who is awaiting with an unconscious bad guy, and tethers the villain to the ropes dropped by the hovering copter. The black harness ropes are shown dangling from the chopper throughout. When McCoy radios to "pull us up" with the villain in view, the once visible ropes are nowhere to be seen. (01:41:40 - 01:42:05)
