Continuity mistake: When Storm tells Gambit to put the discount placard back, he sets it in front of the clerk's computer. When the bellhop comes to get everyone's bags, the placard has disappeared. (00:13:24)
Other mistake: When the hotel clerk is checking Gambit, Storm and Jubilee into their room, he determines that they are mutants by seeing footage of Storm using her powers at the Salem Center Mall from the very first episode. While it's not unreasonable that security footage from the mall could exist showing Storm use her powers, the footage also shows an extremely close zoom-in on Storm's left eye, which is extremely unlikely, unless the security camera somehow guessed she was about to activate her mutant powers. (00:13:27)
Continuity mistake: When Wolverine takes the spear out of Kiyoek's hands, it is silver. When he throws it into the water, it is brown. (00:14:36)
Other mistake: When Wolverine is walking around the camp after Sabretooth attacked it, he doesn't leave any footprints in the snow, even though Sabretooth's footprints are there. (00:14:52 - 00:15:36)
Continuity mistake: When Wolverine is searching for Sabretooth and the captive Inuits, his arms suddenly turn yellow. (00:15:50)
Continuity mistake: When Jubilee, Gambit, and Storm are first shown in their bungalow, there is a coffee table with a couple cups near the edge on the viewer's right, and some magazines on the top corner of the same side. A couple of shots later, the cups and magazines have all moved closer to the center of the table. When Gambit sits up, the magazines have disappeared entirely. (00:19:14)
Slave Island - S1-E7
Continuity mistake: When the lead guard is explaining the inhibitor collars to the new prisoners in the wide shot, you can see Blob at the back of the group, and he is wearing tights, even though he is usually shown wearing a speedo. (00:02:24 - 00:03:41)
Slave Island - S1-E7
Plot hole: After Storm's attempt to escape the Genoshan prison is thwarted, she ends up in the ocean right at the shoreline of the beach, where she is captured by a Sentinel. Aside from the fact that it makes no sense for a Sentinel to be hiding in the ocean in the event that a mutant tries to escape the prison, there is absolutely no way that a two-story tall robot could hide in the ocean right by the beach, as the water would be way too shallow. You can even see that the water level only goes up to the Sentinel's ankle area when it is standing upright in the ocean. (00:03:15)
Suggested correction: Perception. (1) The Sentinel isn't as close as it appears. If it were close, then she would have been caught in its waves as it emerges. Also, she would be looking only at its chest circle. It's several yards away. (2) She washes ashore. She fell from the sky. She couldn't have fallen from that great height into shallow water without hitting bottom. (3) It's also a two-story tall robot. Its weight would sink it into the sand. So it could have very well been down that deep.
Slave Island - S1-E7
Continuity mistake: When the Sentinel drops Storm, there is a female guard standing by its left foot. When Trask is approaching them, it is now a male guard by the Sentinel's foot. (00:03:49)
Slave Island - S1-E7
Continuity mistake: When Trask is approaching Storm and the other mutants, there is a cliff wall behind him. When the shot changes, it is now the sky behind him. (00:03:55)
Slave Island - S1-E7
Continuity mistake: Gambit and Jubilee are shown to be grouping together what appears to be several pieces of malleable rebar. When the shot changes to Gambit reassuring Jubilee that Storm is alive, he is shown to be working with a single piece of rebar. When the shot changes again, they are back to working with a bunch of rebar. (00:05:00)
Slave Island - S1-E7
Continuity mistake: When Cyclops hangs up the phone, he is standing next to a table on which the phone is located. When the shot changes, either the table has disappeared altogether or Cyclops has suddenly moved several feet away from it. (00:06:10)
Slave Island - S1-E7
Continuity mistake: When Cyclops hangs up the phone, the base of the phone shows three rows of five buttons. When the shot changes, there are now only four buttons per row. (00:06:10)
Slave Island - S1-E7
Continuity mistake: When Cyclops, Jean Grey, and Rogue enter the War Room to tell Professor X they are leaving for Genosha, the monitor Professor X is watching is level. A couple of shots later, the monitor is now slanted downwards. (00:08:04)
Slave Island - S1-E7
Other mistake: When Cyclops, Rogue and Jean Grey exit the War Room to depart for Genosha, at the top of the door frame there is a black spec moving around, possibly indicating that there was some debris or a clump of dust on the animation cells or the camera lens itself during filming. (00:08:15)
Slave Island - S1-E7
Factual error: When Professor X is calling Moira McTaggart in Scotland, the phone number he uses is shown to have only dialed the exit code of 011, followed by a fictional seven-digit number with a 555 prefix. Since he is calling from the United States, he would have to dial the country code (44) and area code for the right part of Scotland. Plus UK numbers at that time had at least 9 numbers. (00:08:20)
Slave Island - S1-E7
Continuity mistake: Before the mutants ambush the guards, they are walking in a single-file line, with Sunfire in front, followed by Jubilee, Mystique, Caliban, an unnamed female mutant, and Aurora. A couple of shots later, either Aurora or her similarly-dressed twin brother Northstar is suddenly at the front of the line. (00:08:55)
Slave Island - S1-E7
Continuity mistake: When the Sentinel puts Jubilee in the detention box, it is still dark outside. A couple of shots later and there is a considerable amount of daylight in the sky. (00:09:30)
Slave Island - S1-E7
Audio problem: When Trask is saying "All it requires is an outside power source," his mouth does not move in sync with the last two words. (00:10:20)
Slave Island - S1-E7
Revealing mistake: When Gyrich walks forward to shake the Leader's hand, the ground beneath them is noticeably shaking, possibly indicating a composite shot. (00:10:35)
