Star Trek: First Contact (1996) - 12 mistakes

Factual error: In the scene where Picard opens a viewing port and shows Lilly that she is in a starship orbiting Earth he shows her New Guinea and Australia. New Zealand is missing.

Continuity: In the scene where Picard, Worf and Hawk are outside the ship and want to separate the transmitter dish from the hull, Picard must move a kind of tube out of an console and must turn it from a low to a high position. In one shot the tube is in the high position, in the next shot it is in the low position and then Picard pulls it out and turns it in the high position.

Continuity: When Lilly and Jean Luc are arguing in the captain's ready room Jean Luc breaks the glass cabinet holding the gold models of the previous enterprises with one of the Phaser rifles. It only causes the gold model of the Enterprise D to spin 90 degrees on its hook. The next shot both the gold models of the Enterprise C and D are broken in half.

Continuity: When Picard and Lilly go to the holodeck, the door says "Holodeck". When the Borg enter, it says "Holosuite".

Continuity: When patrolling through the Borg-infested corridors, the type of Phaser rifle that Picard as well as other crew members carry changes back and forth from square shaped to curved shaped barrels.

Continuity: When Worf's spacesuit is cut, a close-up shows it venting from a cut just above the knee. But a wide-shot shows the cut is just below the knee.

Continuity: After all the plasma is vented from the floor of Engineering, Picard's shoes sizzle when he steps on the floor. However, the rungs of the metal ladder he climbs down from, which also would have been submersed in the plasma, do not, and neither do they burn his hands.

Other: Lieutenant Hawk, seated at his console is looking intently ahead at the camera which would be the bridge's view screen from that perspective. But when the shot switches to Picard leaving the bridge, we see that the view screen isn't up. What was so informative about the blank wall that Hawk was looking at?

Revealing: In the deflector dish scene when Worf chops the Borg's arm off with his "sword" the blade obviously doesn't even touch the Borg.

Continuity: As the Enterprise crew walk towards Engineering for the first time, Worf senses the Borg awakening and yells "Ready phasers" before killing a Borg. As that particular drone awakens, we can see it has a needle-like tool coming out of its eye sensor. But when Worf smashes it with his rifle, it has a blue lit-up eye sensor. Furthermore, this drone is seen many times during the following fight sequence after Worf has apparently killed it.

Plot hole: Picard is told that long range sensors are offline, so Enterprise beams down an away team to survey the damage the Borg did instead of just scanning. If they are close enough to beam down, why do they need long range sensors?

Factual error: In the scene after Zefram's ship goes to warp, when the ship is being turned around to return home, Cochran remarks "Is that the Earth? It's so... small" He wouldn't have been able to see it, provided the distance the ship just flew. Warp 1 is the speed of light and in a 1 minute flight, the Phoenix would have travelled over 10 million miles - at that distance the earth would just appear like a bright star.
