Continuity mistake: When Rogue is flying toward Adler's lab, you can see the building is several stories off the ground. When she flies in through the hole in the roof, the interior of the lab is on the top-level, whereas the previous episode showed that the lab was on the ground level. (00:12:55)

Continuity mistake: The exploding playing card that Gambit uses to destroy a few Sentinels and draw the rest above ground is cleverly shown to be the ace of spades (also known as the death card in some folklore), but the card he is shown charging up before the Sentinels see it is the 2 of diamonds. (00:12:10)
Continuity mistake: When Gyrich is in the car trying to get Trask on the phone, he is shown to be sitting in the backseat on the passenger side (note the windows immediately to his right and behind him).

Continuity mistake: When the three horsemen are climbing onto their mechanical horses, Famine's horse is in the middle, and Pestilence's horse is on the right. Once all three have all been individually shown to be mounting their horses, Famine and Pestilence have swapped places. (00:06:08)
Continuity mistake: When Gambit is saying "Someone may be tracking us," the snaps on both shoulders of his jacket are colored blue, when they should be the same brown color as the rest of his jacket. (00:11:45)

Days of Future Past: Part 2 - S1-E12
Continuity mistake: When Mystique starts walking away from Rogue, her footsteps are audible, and she takes about four steps. When the shot changes to a closeup of Rogue asking why Mystique tried to turn her into one of Apocalypse's slaves, if you listen carefully, you can hear Mystique take about ten more steps. When the shot changes again, Mystique is suddenly only a couple steps away from Rogue. (00:18:58)
Continuity mistake: When Jean is using her telekinetic powers to rescue Senator Kelly from Master Mold's lab, she drops him on the floor in the middle of the lab.

A couple of shots later, Jean and Kelly are now standing at Master Mold's feet. (00:15:42)
Continuity mistake: When Gambit is asking Xavier why the X-Men must all die to save Senator Kelly, the top of Wolverine's mask is incorrectly colored blue. A few shots later, this portion of the mask is correctly colored yellow, but then the portion of his mask by his right cheek is also yellow, when it should be black. (00:09:48)
Days of Future Past: Part 2 - S1-E12
Continuity mistake: After Blob knocks Cyclops to the ground, Jean helps him up, and the two of them are standing a step away from Blob. The shot changes to Blob pointing and laughing for roughly a second, and when the shot changes again, Cyclops and Jean have disappeared, with not enough time to have moved offscreen. (00:12:20)

Continuity mistake: When Gyrich's gun slides over next to Cyclops' feet after Wolverine tackles him, you can see Cyclops, Rogue, and Storm are standing at the entrance of the Lincoln Memorial. When the shot changes, the three are no longer near the entrance. (00:09:07)
Days of Future Past: Part 2 - S1-E12
Continuity mistake: When Xavier's watch magnetically clings to his hoverchair, the body of the watch is pointing at 1 o'clock. In the next shot, it is pointing at 12 o'clock, the minute hand has advanced roughly 4 minutes, and the watch has also moved down the chair and to the right a few inches (note the contour lines on the chair as the visual cue). (00:20:39)
