Mistake #1
When Gene's bodyguard (the one with the moustache) shoots Slasher and Duke, just before Slasher is shot the bullet hole effect is visible on her forehead (sightly concealed by make-up) just before the actual 'shot'.
Mistake #2
In the scene where XXXX and Lucky are in the park waiting in order to assassinate Dragan - after Dragan shoots Lucky and is talking to XXXX on the phone, the bag that Lucky was resting his gun on changes size and shape between shots.
Mistake #3
In the scene in the park where XXXX and Lucky are waiting in the bush - when Lucky looks through his telescopic sight at Dragan it appears to be raining, however, when we return to the wide shot of the two of them in the bush, it appears to be a rain-free day.
Mistake #4
When XXXX is in his apartment dressed and ready to go to his accountant, he answers his cell phone, speaks, and then throws it on the desk. After the visit, when sitting at Greenwich Observatory he answers his cell phone, which should still be in the apartment.
Mistake #5
When XXXX is in Greenwich Park with Mr. Lucky and he gets shot, Dragan shoots at the grass in front of XXXX. Grass is thrown into the air, and you can see white smoke coming from an explosive for the special effects.
