Revealing mistake: As several camera angles show, Sawyer's makeshift stretcher was made by drilling multiple holes in the upper frame struts, through which was threaded rope made from dried roots or vines. The cast who supposedly constructed it were not carrying power drills among their primitive implements.
One of Them - S2-E14
Visible crew/equipment: When Sawyer searches for the tree frog in the jungle he moves away from the shot towards the trees and when he comes back closer to the camera you can see the shadow of the cameraman on the tall grasses on the lower right.
Revealing mistake: When Ana Lucia is threatening "Henry Gale" in the hatch cell; every time he moves and his makeshift shirt slips, you can see a line on his right upper arm where they applied make-up. Apparently he's wearing makeup on all the exposed parts of his face and neck to make him look sunburned, exposed to the elements etc. This is not just a normal suntan line, as his shirt wouldn't normally fall down that much out in the open and he's been inside for days now.
One of Them - S2-E14
Revealing mistake: When Sayid and Locke are talking to Henry Gale in the hatch, just as Jack comes in and finds them, the front part of the arrow supposedly piercing Gale's shoulder is at a different angle to the back part. This is visible in a number of shots.
Continuity mistake: Charlie takes a step and breaks the virgin statue. Half a second later it's broken in a totally different way. (00:23:10)
Continuity mistake: When Eko finds the "priest" on the ground, his white clerical collar is properly on. In "Duex Ex Machina" when Locke causes the skeleton of the Nigerian "priest" to fall from the tree, the collar comes undone, and the clergy shirt is rumpled.
Continuity mistake: When the doctor takes the polaroid picture of Hurley and Dave, there are others patients behind them, right in front a window. But at a further scene, when Hurley sees the photo 'without Dave', these other patients are missing too.
Visible crew/equipment: As Locke and Eko descend down the hatch a safety cable can be seen supporting Locke.
Collision (a.k.a.Old Habits) - S2-E8
Continuity mistake: When Sayid is carrying Shannon's body back to camp, the back of her shirt is almost without blood. Two minutes before, when Sayid picked Shannon up from the ground, her shirt was blood covered.
Continuity mistake: Just before Michael says "You're going to pull the bullet out with your bare hands?", Sawyer's hair is very wet and pulled back, as if it were in a pony tail. When the camera switches back to Sawyer saying "You got a better idea?" his hair is a lot drier and covering his face. In the next shot, it is pulled back again. (00:15:10)
Continuity mistake: In S.O.S., Locke is trying to remember the map he saw on the blast door. He ignores the blaring alarm until Jack reminds him, and Locke inputs the code and hits EXECUTE. The camera cuts to a shot of the numbers resetting, and then back to Locke, and he takes his finger off the EXECUTE button a second time. (00:02:30)
Continuity mistake: When Jack and Kate are discussing who should stay with Sawyer and who should go to Shannon's funeral, as the camera goes back and forth between the two the towel on Sawyer's forehead is there, then not, then back again through the whole scene. (00:07:30)
Man of Science, Man of Faith - S2-E1
Plot hole: Sawyer pulls the bullet out with his bare hands, we are led to believe, through the cut the bullet made. When you are shot, the flesh immediately seals up, meaning you would need a knife or something like that to get it out. Sawyer only had the gun, as he could not have hidden the knife AND the gun. (00:15:25)
Continuity mistake: In episode 2-19 SOS When Bernard is talking to Rose after she questions him in front of the group about his "sign" when the close ups are on Bernard you can see that it is raining quite heavily in the background, but when it's close up on Rose it is not raining. It doesn't begin to rain in the episode until much later.
Other mistake: When the doctor stops Sun on the streets to tell her that Jin is the one who can not have children, at one point the subtitles say "You're husband." The correct spelling would be "Your".
Continuity mistake: In the scene where Sawyer collapses from his bullet wound, he collapses onto his knees and then twists so that his good arm is towards the ground. From there, he rolls to his back. Then the camera angle changes so we're looking at Michael and Jin running towards Sawyer from the front. Sawyer is now on his good arm's side.
Man of Science, Man of Faith - S2-E1
Continuity mistake: At the start we see Desmond in the hatch. When the explosion goes off he gears up and runs over to a machine where he turns the music off. The shot of the shelf is a flipped shot. (00:02:28)
Continuity mistake: In the scene where Shannon and Sayid are next to Boone's grave, in one shot there is a necklace on the cross and in the other it disappears. (00:23:40)
Live Together, Die Alone, Part 2 - S2-E24
Continuity mistake: In '?' when Locke put his map of the stations in the chute, it was not folded. However, when Sawyer finds it in this episode, it is folded.
Answer: He was eating a peice of an orange with the skin still on.
