Visible crew/equipment: In the shot where the 4x4 flips, you can see a stunt driver and a dummy inside the vehicle.
Continuity mistake: When Saints's men are killing Castle's family, there is a shot of Frank and his dad shooting at one of the guys behind the barbecue stand. In one shot Frank and his dad shoot the salad bowl and most of the salad comes out, then in the following shot the salad has magically reappeared.
Continuity mistake: When Saint's men murder Castle's family, the man who tried to escape on the motorcycle is shot and falls off next to the motorcycle. The motorcycle slides and comes to rest with the back of the motorcycle facing the large deck and ocean. However, when Castle chases his wife and son, he picks up the motorcycle, and it is turned around with the front facing the ocean.
Continuity mistake: When Frank is pulling down the gravestone with a chain, in the shot from the front, William's is to the left about a foot away and Maria's is to the right, the same distance. In the shot from behind the stone, there is another stone you can just about see on the right of the screen and it can't be William's because this stone, or something, is directly behind Frank's.
Continuity mistake: When the cops turn up at the firearms deal, someone says, "Your under arrest," and there are two to three cops. When Frank says his line, the camera cuts to an overhead shot and there are now 6 cops all grouped together standing only a few feet from Bobby, Frank and the others.
Continuity mistake: When Frank's family is being attacked, Frank and his father are inside the house fighting with some thug hiding behind the barbecue stand. At one point a shotgun shot is visible in the black metal lid on the left of the stand. In the next shot, the lid is intact, and then when the gas bottles blow up, it's shot again.
Continuity mistake: At the end, when Howard Saint is being dragged behind the car into the lot full of burning cars, he is catching on fire in a close up. Then in a far shot and Saint is no longer on fire, but in the next close up he is on fire again.
Visible crew/equipment: When Howard Saint's men begin to chase after Frank's wife in their red 4x4, just after a couple of guys jump in the back, the camera pans forward to get a view of the driver. As the camera pans forward a boom mic with a large pole is visible in the reflection on the car.
Continuity mistake: When Frank crashes his Pontiac after speeding away from Harry Heck, Heck pulls up and walks up to Frank who is climbing out of his car. As he walks up, a piece of car is on the right side of Heck, but after Frank kills Heck, it cuts to an overhead shot and the piece of car is now on his left.
Continuity mistake: Whilst being chased by Harry Heck, Castle drives through a railroad gate. As he does so a piece of wood seems to get jammed or stuck on his right headlight. In the very next shot, the piece of wood is nowhere in sight, not even on the road.
Continuity mistake: The bullet-hole scar on Frank's chest moves closer to, and further away from his sternum several times during the film.
Visible crew/equipment: When the bad-guys blow Frank up towards the beginning, as they drive away the camera pans with the car, and you can make out the shadow of several crew members and possibly the camera at the bottom right of the screen.
