Revealing: The following take place in F/A-18s. After Jimmy says, "I got you covered, big daddy," there is a close-up of his gloved hand as his thumb presses the launch button. Later, when President Whitmore fires his last missile (with negative impact) there is a close-up as his thumb presses the launch button, and then a minute later there is a close-up of Russell's hand as he presses the launch button (resulting in launch failure). The last two close-ups are the very same shot as shown earlier, only the last two shots are flipped the other way.

Continuity: Aboard Air Force One, when David feels nauseous there is a telephone between his seat and his father's, whose cord gets twisted between shots, though it hasn't been touched.

Visible crew/equipment: At the White House, when they all watch the Soviet Special News, in the close-up of the TV's staticky reception of the news feed the reflection of White House staffers is visible. Right between the woman in a white blouse and the man in suit and tie, is the camera and crewmember, wearing light-colored short sleeve shirt and baseball cap, moving about.

Visible crew/equipment: When Dr. Okun is about to unlock "the vault", and says, "The freak show," a crewmember wearing a black and white striped shirt is hiding under the vault's floor, right behind Okun. (Only visible on fullscreen DVD.)

Revealing: In the shot of the orbiting old Russian satellite, just before it explodes at the hull of the alien mothership, the two wires at the top of the miniature satellite model are visible (and no, they are not two very long antennas), as it passes from the left to the right of the screen.

Other: When the huge alien ship settles over the White House there is an exterior wideshot of the grounds. At the bottom of this shot it's funny how there are many tourists - adults and children, just milling around in front of the gate and across the street with a van driving along between the two sides, and not one has any sort of reaction to the alien ship. This real shot of the White House (some shots had smaller-scale models) had the CG ship edited in during post production. (Visible on fullscreen DVD.)

Continuity: When Jasmine grabs Dylan out of the car, his sneakers are white/black with black laces, but when she is kicking the maintenance door, his sneakers are white with white laces, then it switches again in following shots.

Visible crew/equipment: When President Whitmore, General Grey and the rest return to the containment lab to see the live alien, Major Mitchell stands directly in front of the smoke filled lab and the camera equipment/crew are visible in the reflection on the glass. President Whitmore, General Grey and a few others are supposed to be the only ones in front of the three aliens' liquid chambers. (Only visible on fullscreen DVD.)

Continuity: When Russell boards the F/A-18 and when he is airborne - such as when he salutes Major Mitchell (who is back at command center), he wears his Hawaiian style short-sleeve shirt and is gloveless. After he says, "Eagle 20, Fox 2," in the close-up as he presses the launch button (resulting in launch failure), the arm shown wears both a green jumpsuit and gloves, neither of which Russell actually wears.

Visible crew/equipment: When President Whitmore returns to the containment lab to see the live alien, just as Major Mitchell and a Secret Service Agent walk to face the smoke filled lab, the actor's mark is visible on the ground as the Agent steps up to it. (Only visible on fullscreen DVD.)

Continuity: When the White House is being evacuated, as Connie runs down the stairs in the shot facing her, she is speaking with a woman to her right, but in the next shot from behind the woman has vanished.

Continuity: In the interior shot, when Jasmine tries to explain why she doesn't want Steven to leave she pulls open the white curtains, to view the alien ship through the window (the window closest to the door), and as Steven walks out the front door she stands by that open window. Then when it cuts to the exterior shot, in an instant that window's brown venetian blinds are now down and the white curtains are drawn closed, as Steven walks down the lawn.

Continuity: Aboard the AWAC, after the pilot sees the fireball emerging from the clouds, there is a wideshot of the interior with the cockpit in the background. The pilot is not wearing the dome-shaped helmet, note the distinct outline of his hair, whereas in the close-ups he is wearing it.

Revealing: In the exterior shot of Air Force One and its accompanying jets in the air, just before the shot of David getting nauseous aboard Air Force One, something appears along the entire bottom of the screen, which looks like the edge of film strip. Whatever it is, it shouldn't be there. (Visible on fullscreen DVD.)

Continuity: In the Oval Office, when General Grey says, "They're tracking another one off the California coastline," as Connie rushes in, the lamp on the table beside the couch is gone. Then in the overhead shot of the Oval Office the lamp is back on the table.

Continuity: On the AWAC, in the close-up of the pilots' hands at the console, they are wearing gloves that reach up to their wrists. When the fireball shatters the windshield, their gloves are much longer now - closer to their elbows.

Audio problem: At the White House, when Connie hangs up on David, as the President stands at the podium behind her, his mouth and the words we hear are not in sync. We are seeing and hearing him live, not on a delayed news feed.

Continuity: In the Oval Office, when David says, "They're using our own satellites against us," the grandfather clock is about a foot away from the doorway behind him. In the previous wideshot, when Alex appears at the doorway, the grandfather clock is farther to the right, nearer to the other curtained doorway.

Continuity: After David makes a mess in the Area 51 alien attacker's hangar, when he is sitting on the ground facing Julius, the liquor bottle label changes directions in his hand.

Audio problem: After David's rant about burning the rainforests, etc, when he's on the ground Julius takes the bottle out of David's hand and we hear the sound of the bottle hitting the floor. But Julius still has the bottle in his hand, then puts it down two shots later - with no sound obviously.
