Factual error: In the film, Sgt. Jack Lupino is depicted as a United States Marine Corp Sargent. However, when Max is watching an interview with Lupino it shows him wearing either a Gunnery Sargent or Master Sargent chevrons. Not only that, but the chevrons happen to be upside down. No US Marine would ever make a mistake like that.
Visible crew/equipment: When Max meets a man in a car who invites him to jump in, they go to the place where Natasha was killed. When the car drives in the alley and we see it from the top of the building (the camera angle), the camera filming them is visible in the reflection on the car's roof (it's mounted on a rod hanging high above the alley). (00:18:25)
Continuity mistake: When Max is being beaten by Natasha's sister, she gives him a good whack to the right side of his face, leaving him bloody. But in the scenes to follow there is no mark or blood on his face.
Factual error: As the vehicle drives on a street of 'downtown New York', on the right side of the scene as we pass store fronts, one can see the familiar symbol of the American Automobile Association - except it has CAA - Canadian AA. Canadian viewers, especially those from Toronto who recognise the city where this movie was shot, will no doubt smile at this oversight. It's early in the movie - before all the action really starts, I believe before Donal Logue's character is killed.
Other mistake: When Max Payne is in front of the "NYPD" station, and then gets in a car with his partner, they drive down the street for a split second and you see a TTC (Toronto Transit Commission - Ontario Canada) wheel transit bus, and Canada Post Mail delivery truck in the background to the driver side of car. The TTC bus is red, white black and the mail truck is red, white and blue. (00:17:15)
Continuity mistake: In the final scene on the rooftop helipad, Mark Wahlberg raises his semi-auto handgun and shoots Beau Bridges once, straight through the heart. Bridges is dead before he hits the ground: His knees buckle and he falls face-down, with both arms hanging limp at his sides. The camera cuts to a close-up of Bridges face-down on the helipad, but now his left arm is raised with his hand directly in front of his face. That would only be possible if he fell with his left arm raised after he was shot.Charles Austin Miller
