Continuity mistake: When Kersey shoots Vasquez behind him we see the squibs under his shirt make the classic plus shaped holes in that shirt, but every time we Vasquez's body after that there are no holes in his clothes at all and the bloodstains also move between the time he's seen on the floor and the time he's unpacked from the crate he ends up in.
Visible crew/equipment: When Blankman and his brother escape from the bank just before it explodes they are diving on the ground to escape the explosion. You can see that Blankman's brother is a stunt double. (01:04:30)

Continuity mistake: In the credits, Cammy has been mispelt "Cammie"
Factual error: When Jack (Molloy) is at work in the call center, he uses his mobile phone to take a call.

Continuity mistake: During his monolog in the scene on the airplane, Briggs introduces Wayne as a private but, in the next scene when they wash up on shore Briggs addresses Wayne as lieutenant.
Revealing mistake: When they are stopped after curfew by the Mohawks, Hawk jumps at the window and orders them to give them 50 bucks to go on, and they accept credit cards. When saying this, you can see the dividing line between his real skin and the fake head cap that supports the actor's fake hair.
Continuity mistake: At the beginning of Chen Zen's trial there is a shot of the guards closing the courtroom doors. Then there's a wide shot of the whole courtroom and the guards can be seen in the background closing the doors again. (00:41:01)
