Continuity mistake: Eve and Troy visit Mikey's grave. When they first go out to the car, it's cloudy and raining, but they get to the cemetery and the sun is out and everything is completely dry.
Audio problem: When Travolta steals the speed boat there is a wide shot of him driving away and you can see Cage running towards him in the top right of the screen. You can hear Cage fire his gun but the muzzle flash doesn't appear until a second later after the gun is fired.
Continuity mistake: When Castor (as Sean) grips the speargun, in the following close-ups, the sling ends (with its wishbones) differ - just note the rings around the rubber ends.
Revealing mistake: When Castor is pushed into the blowing heat from the plane engine by Sean and is thrown back, the man that lands against the grill is so obviously the stunt double; he has a different hair cut than Castor and really doesn't look anything like him.
Continuity mistake: During the cemetery scene where they visit the son's grave, you see a wide shot of them walking between the stones. There are leaves on the trees and neatly trimmed grass. When we see a close up of the stone and the plaque in the ground, a hand reaches down to brush the leaves off so they can read it, and there are dead leaves all around - but there were no leaves on the ground in the wide shot.
Audio problem: When Castor wakes up from his coma, he reaches up to his face and pulls out the nose plugs that fed him oxygen. Strangely enough, his heart monitor stops beeping when the plug is removed.
Continuity mistake: When Castor arrives at the airport, behind him there is a parked car in front of the building which on it reads "Welcome to Southern California International Airport", that disappears and reappears.
Continuity mistake: After Sean types "case closed" on Castor's file, Dr. Miller walks into Sean's office and holds out Pollux's Zip Disk for Sean to take. In the next close-up, the Zip Disk has flipped over and faces the opposite way.
Continuity mistake: After the incident with Karl, when Castor (as Sean Archer) and Jamie are in the living room, he opens the cigarette case and offers her one. The way he holds the case noticeably differs between shots.
Revealing mistake: At Erehwon, Sean (as Castor Troy) is given steel magnetic boots to wear, for the prison's important security feature. There is a close-up of these heavy duty boots during his 'exercise'. Then, when he is taken to the clinic there is another close-up, and there are a number of changes to the boots style. More importantly, one of the side "bolts" has fallen off, revealing that it was merely glued on the prop boots.
Revealing mistake: Just as the red speedboat heads toward shore, before it crashes, the white and red truck cranes are on the dock and the white crane arm is angled backwards over the dock. In the shot facing the speedboat, as it explodes, that crane arm is now angled the opposite way, over the water, since it was used in the stunt.
Factual error: In the scene in the hall where there are is a circle of mirrors where Castor and Sean engage in a shootout, there is a mistake as the FBI agent fires at Castor. The FBI agent is holding an M16 or M4 assault rifle with an M203 40mm grenade launcher. He fires two consecutive shots within a second of each other. This is impossible as the M203 attachment only holds 1 shell at a time and would take at least 5 seconds to grab another round and reload and fire again.
Visible crew/equipment: When Cage throws Pollux through the ceiling window, the support wire is seen in front of Cage as he's hanging from the edge.
Revealing mistake: In the hall of mirrors Travolta runs behind the mirrors in order to get the drop on Cage. Cage starts shooting, but when he stops and lowers his arm the muzzle flash (and possibly the gunfire as well) from his gun continues as if he's still firing.
Continuity mistake: During the runway pursuit, there is a shot from behind Castor Troy as he fires on Sean's chopper, and there are four bullet holes on the windshield. In Sean's close-up the four bullet holes change position.
Continuity mistake: When Cage is rolling down the runway he appears to be controlling the direction of the aircraft by turning the yoke. An aircraft is controlled on the ground via rudder (vertical stabiliser) controlled by the feet of the pilot, and nosewheel steering, also controlled by the feet (rudder pedals) of the pilot (sometimes also with a steering wheel on the side of the cockpit). Moving the yoke simply alters the position of the ailerons, which will not steer the aircraft on the ground.
Character mistake: When Troy is getting the bomb ready, the screen shows it will blow in 216 hours, which is 9 days. Yet the agent tells Archer it will blow in 6 days.
Deliberate mistake: When they fight in the hangar and Troy is thrown back by the jet engine, his face and other parts of his body should have been burnt quite heavily. Such a jet engine has temperatures higher than 450°C about 5 meters away, and Troy is even closer than that.
Other mistake: When Troy (as Archer) goes to defuse the bomb, the #1 key lights up before he even presses it.
Continuity mistake: In the scene where Cage and Travolta are fighting on the dock, Cage stabs Travolta with the speargun (before he fires it). If you look at the spear after Travolta is stabbed, there is blood on it. Then in the next shot, the spear is suddenly clean.
Chosen answer: It's obvious that enough time hasn't passed for a trial of such magnitude to take place, meaning that the brothers have been remanded in custody to await trial. They should have been arraigned but we don't see that onscreen.
