Continuity mistake: When Jack drops to his knees, after removing the undershirt, one white shirt lies stretched out horizontally on the ground directly in front of him, with both knees centered in front of it; the other shirt is off to his right (viewer's left), with the undershirt he drops. Three shots later, still on his knees, all three shirts lie rumpled to his right; eleven shots later, the single white shirt once again lies horizontally directly in front of him, in the very same position as the earlier shot.
The Greater Good (a.k.a. Sides) - S1-E21
Visible crew/equipment: After Sayid and Essam pull into the garage, when Sayid leaves through the back of the white van and closes the door, there is a lovely clear reflection of the cameraman and camera reflected on the door. (00:34:25)
Whatever the Case May Be - S1-E12
Continuity mistake: When Kate and Sawyer happen upon the lovely waterfall, Sawyer removes his shirt and he has the bandage tied round the stab wound on his upper arm. When underwater, there is a different dressing on his arm; it is snugger, with no ends - most likely an elastic type to stay put during the underwater shots. (00:02:50 - 00:04:15)
Continuity mistake: When Sawyer and Sayid are fighting and Jack tries to pull Sawyer away, Sayid changes from holding onto Sawyer's shirt to holding onto his pants between the shots. (00:07:55)
Exodus (2) - S1-E24
Visible crew/equipment: After Kate throws dynamite down the hole, when Jack pulls Locke up, the green straps (for device used in the stunt) going round Locke's pant leg are clearly visible. (00:46:40)
Whatever the Case May Be - S1-E12
Continuity mistake: On the beach, when Shannon questions Boone about his and Locke's whereabouts everyday, Boone wears a sleeveless tee shirt with large Asian characters on the front. Then, when Boone kneels beside Shannon the entire design actually disappears. (00:09:35)
Tabula Rasa - S1-E3
Continuity mistake: When Kate leans over the unconscious marshal he wakes and chokes her, and when Jack subdues him the marshal's large head bandage falls off. When Jack squeezes water into the marshal's mouth, the bandages are wrapped perfectly round his head, yet when Kate stands up the bandages are off again. (00:19:30)
Continuity mistake: When Jin offers food to Claire while she is writing in her diary, we see her writing while holding the diary in her hand. When it cuts she holds the book in both hands, place it in her left hand and begin writing again. (00:23:40)
Homecoming - S1-E15
Continuity mistake: When Jack shows Locke the case with guns, the bar trim beneath the handle is whole and unbroken. However, in "Whatever the Case May Be" when Boone tries to open the case without the key, the trim beneath the handle breaks off and is damaged. (00:27:45)
White Rabbit - S1-E5
Visible crew/equipment: In the episode where the doctor tries to save the woman who is drowning, when he enters the water for the second time just as he says "there's someone else out there", you can easily see the keel water of the boat or Jet Ski that is filming him. (00:02:45)
Continuity mistake: The white tape round Charlie's fingers, that first read "fate" and later "late", drastically change their appearance - such as the size and shape of the letters, and the color and condition of the tape, in numerous consecutive shots.
Continuity mistake: When Shannon is looking for Boone but instead finds his "jungle pal" Locke, he is gutting his dinner and gets blood on his face. The blood on Locke's face repeatedly changes, such as in one shot there's a small clot of blood beside his eye, and in another shot the blood is lower and larger. (00:19:00)
The Greater Good (a.k.a. Sides) - S1-E21
Continuity mistake: Sayid wears a black tank top when he speaks at Boone's burial, and it has a wide shallow tear and small hole at the collar. When he walks away with Jack, who is complaining about Locke, though the style of top is identical, now the tear is narrower and deeper, and the hole is bigger. Throughout this episode the tear, on the tank top Sayid wears, alternates, and the hole even disappears. (00:08:50)
Visible crew/equipment: As Jack, Michael, and Charlie walk up to Hurley, the camera goes to the left of Hurley and you can see a road to the right of him and directly behind him a fence. If you look closely you can see a car parked under one of the trees. This can be seen in both the T.V. and DVD versions. (00:18:20)
White Rabbit - S1-E5
Continuity mistake: When Charlie and Hurley are talking to Jack about the water, Jack then shouts something like, "I'm not making any decision," and in the background two people walk by - they move from right to left. After a cut to Charlie and Hurley when Hurley asks "Why?" it cuts back to Jack, and the same two people walk from right to left again. (00:10:30)
Tabula Rasa - S1-E3
Continuity mistake: When Kate pulls Ray from the burning pickup, in the first shot as she drags him across the grass his overall suspenders are not on - they are not clasped shut. However, as Kate drags him, a few shots later the suspenders are properly clasped on. (00:30:50)
Continuity mistake: When Kate, Jack and Charlie find the cockpit with the pilot, the blood on the pilot's face differs between shots, such as in the shot from behind, when he turns to show the location of the transceiver. (00:39:15)
Tabula Rasa - S1-E3
Revealing mistake: When Kate pulls Ray from the burning pickup, he has bloody bruises at the center and right side of his forehead. As she drags him across the grass, in the shot when she grunts, the bruises on his forehead are at the center and left side of his forehead. This shot is flipped. (00:03:15)
Whatever the Case May Be - S1-E12
Continuity mistake: After Kate and Sawyer find the corpses underwater, the marshal's Halliburton case that Sawyer retrieves has two protruding wide silver clasps to the handle's sides, and a thin, narrow handle with flat pivots at its base. The case that Kate tries to steal from Sawyer, and in all the following shots, has a very different style top - NO clasps whatsoever, and it has a round, wide handle with raised round pivots. The Halliburton with clasps is also seen in "Exodus 1" with the airport security officer. (00:06:10 - 00:12:20)
