Continuity: In the scene where the Asian gang is ramming Porter with their car, when they hit him the windshield gets smashed. When they all get back in their car and drive off the windshield is fine.

Continuity: After Porter leaves the house of Fairfax, a cab pulls up with Stegman in it. When the cab pulls up the windows are all clear. In the next scene when Porter opens the cab door the windows are all frosted over.

Factual error: Porter cuts the fuel line on the car but in reality, fuel lines are mostly steel except for a few joints which are only a few inches long. There would be no rubber tube long enough to be cut as shown in the film.

Continuity: In the scene where Val Resnick points to the button of the door phone, which Porter stained with blood, we can see that it is number 403. But actually Rosie lives in room number 404. You can see it earlier, when Rosie opened the door to her apartment in order to meet Porter.

Continuity: When Porter leaves the apartment of the prostitute, and returns busting through the doorway only to find Val beating up the girl, he then shoots Val in the shoulder. As the shots switch back and forth, from Porter and the others, the door he just came through is open wide in some scenes, and almost shut in others.

Factual error: When the cab that Porter and Stegman is attacked by the Chinese gang members, the cab is shot up and Porter escapes and proceeds to attack the Chinese gang. He uses his .44 caliber pistol he bought in the beginning of the film and a Glock 9mm (I believe). In the course of his attack, he fires about 10 shots from the .44 cal (without reloading, it only holds 6), and about 20 or so from the Glock (holds 17, unmodified anyway). Only when he goes to shoot Pearl, does he run out of ammo. Convenient isn't it?

Continuity: When Porter enter Stegman's office we see Stegman's bodyguard sitting with his right arm on his knee. When it cuts to a shot in front of him he holds his right hand to his mouth.

Continuity: Kris Kristofferson goes to Porter's apartment to find his son. When the phone starts ringing it is right on the edge of the table, right behind the ashtray. However, when the scene gets to where he bends down to answer the phone, the phone is in the middle of the table NEXT to the ashtray.

Continuity: When Stegman says "He said his name was Porter" to Resnick, you see Resnick's mouth is open. You also see Stegman turning his head to sip from his glass. When it cuts Resnick has his mouth closed and Stegman turns his head again.

Visible crew/equipment: When Porter and Rosie arrive at the hide out apartment and Porter says "He'll live, how are you?", you can briefly see the boom mike shadow move on the door.

Continuity: When Porter, Val and Lynn make the 'hit' on the Chows in the beginning of the movie, their car changes from a 1970 Nova to a 1973 Nova. It is apparent by the differences in the grill: There are square, orange parking lights in the grill on a '73 and there are no parking lights in the grill of a '70.

Continuity: In the scene in Risie's apartment with Val, Val is holding a gun to Rosie's head. It keeps switching from her head to his knee between shots.

Factual error: Near the end of the movie, when Porter is forcing his way out of the trunk of the car he was trapped in, he forces his way through the backseat and makes a call from the phone in the back of the car to the phone connected to the bomb in the hotel room. The phone he uses in the car is a rotary phone. These phones can not be used in wireless environments. It was an inaccurate prop.

Continuity: In the scene where Val Resnick is looking at buttons of the doorphone we can see that there are only four rooms (from 401 to 404) on the floor where Rosie lives. But the room which is opposite Rosie's room is 407. You can see it when Val comes in Rosie's room with a gun.

Continuity: In the scene where Val Resnick is kicking through the car window he has free hands. After Porter called him Val already holds grampus in his hand which Porter left on the back seat of the car.

Visible crew/equipment: In the scene where two cars crash. Before the hit, but right after the scene when the Chinese driver pressing down on the brake you can see a steel rope attached to the bottom of the car.

Visible crew/equipment: In the scene where Porter talks to Rosie in the phone, after talking to Michael (the bartender at the hotel), you can see the microphone in the left upper-corner. This is only visible in the 4:3 (Fullscreen) version.

Continuity: When Porter slams Michael's fingers, the dollar bills Porter threw are on the counter. Suddenly, the bills are gone. Then they re-appear when Porter gives them to Michael.

Continuity: After the Asian gang has hit Porter with their car, the windshield is totally smashed. But from inside, when Porter flies off the hood, there are only a few cracks in the windshield. And when it cuts again, it is totally smashed.

Continuity: When Porter is tied to the chair being beaten up he is wearing boots and his legs are not tied to the chair. In the next few scenes when Mr. Bronson shows up with his hammer, now Porter has no boots on his feet and his legs are tied to the chair.
