Revealing mistake: When the second helicopter is blown up you can see it is the same helicopter that was blown up the first time. The writing on the helicopter is reversed compared to the first helicopter.
Continuity mistake: When the fighting begins Jackie jumps under a table. You can see there is a lot of stuff on the table. In the next shot when Jackie grabs the table in order to throw it all the things are gone.
