Other mistake: Ninja Master David does his knife-throwing parlor trick on Martin the Russian Mobster, freezing him in terror with his shuriken. They fight off, but the yellow jacket henchman distracts him. David manages to kick the macguffin box off Martin's hand, and you can see the box tumble a couple of steps away from the three-way fight. Still, Becky gets it in the next shot from the original hiding spot, without anyone in sight. David gives chase to her and the two old dudes but can't catch up to them. (00:29:30)
Other mistake: To get to the hiding place of Tanaka's macguffin, both Becky and Tanaka are in the passenger seat of the car. The driver is never shown, nor referenced or addressed, and the car just sits there parked. (00:18:10)
Other mistake: When Tanaka is kidnapped at the airport, someone shoots one tire and then the driver in the head - however, it's not shown nor explained who could do that, and in fact, it's inconsistent with what is shown after, in particular the direction of the shots (the tire could only be shot from the street, the guy from the airport).
