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.
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.
Continuity mistake: At the end of the scene in the gym of the mental hospital when Hurley and Dave talk, in the background there is a guy sitting on the floor in a yoga-like position. His exact location changes between shots, as you can tell by the ground-lines. First he sits on the red line, next to where the blue and the yellow lines cross, then he sits about 5 feet further to the right, and finally he is back exactly on the same spot as in the beginning.
Continuity mistake: When Libby kisses Hurley at the cliff, there is a strand of Libby's hair which you can see hanging freely over her left cheek when the camera is on Hurley. When the camera is on Libby you see the same strand pinched between their heads. Then as the camera switches back on Hurley the strand hangs freely again. It's not possible that this happened only through the force of wind as their heads are stuck together quite tightly throughout the whole kiss.
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: 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.
Visible crew/equipment: When Jack and Co. approach Sawyer for the guns on the beach, Sawyer's glasses reflect a mass of people stood directly in front of him while only Jack is directly in front of him. (00:31:00)
Visible crew/equipment: As Locke and Eko descend down the hatch a safety cable can be seen supporting Locke.
Continuity mistake: When Locke and Mr. Eko watch the Orientation video in the pearl station Dr Chang has both arms and the screens behind him show people working in the swan hatch. His arm was badly damaged in the incident before the swan hatch was built and he should.have had a prosthetic arm when the pearl video was made.
Live Together, Die Alone, Part 1 - S2-E23
Continuity mistake: When Des is being released from prison, in one shot he is holding the picture with one hand, and with two in the next shot. (00:05:20)
Live Together, Die Alone, Part 1 - S2-E23
Factual error: The prison Desmond is released from looks nothing like any British prison, let alone the British military prison (the "Glasshouse"), which is more of a training camp than a traditional prison. The guards wear no cap badges on their berets (all British service personnel wear cap badges) and their berets are worn almost vertically on their heads, whereas British berets are pulled hard to the right. The NCO who releases him is credited as a "master sergeant" in the episode credits - an American rank which has never been used in the British Army. (00:05:30)
Live Together, Die Alone, Part 1 - S2-E23
Continuity mistake: When Jack confronts Michael and grabs him by the chest, the way he holds him changes between shots. (00:37:40)
Live Together, Die Alone, Part 1 - S2-E23
Continuity mistake: When Sayid is praying, his hand positions change between long and close-up shots. (00:40:25)
Live Together, Die Alone, Part 1 - S2-E23
Continuity mistake: In Episode 2-23 Live Together, Die Alone When Mr Eko runs out of the hatch when John and Desmond are faking a lock down, you see Eko put his club in his belt right in the front of his pants. In the next scene as he passes out of the door the club is gone and then when he runs back to the door as it is closing he is holding it in his hand as he drops it and it falls under the door.
Live Together, Die Alone, Part 2 - S2-E24
Continuity mistake: When Ecko throws the belt at the wall, the position changes to when Charlie grabs it. (00:05:40)
Live Together, Die Alone, Part 2 - S2-E24
Continuity mistake: As they are walking through the jungle, Sawyer goes to pick up a doll. He reaches down and nearly touches the doll. But in the next shot Kate grabs his arm, to stop him, before he even bends over. (00:18:00)
Answer: He was eating a peice of an orange with the skin still on.
