Continuity: In numerous shots of individual characters, while on the island, the sweat stains on their clothing significantly and repeatedly change, or disappear and reappear between shots.

Continuity: On the airplane, the same passengers are seen in numerous shots with different main characters, and purportedly Kate and Marshal Mars (row 25) are in the same cabin on the opposite side of Jack, Rose and Locke (rows 23 & 24), yet are not seen in shots where they should be seen - though in shots of Jack and Rose, during the turbulance, the same woman and man (behind Locke) fly up as in the Kate and marshal shot. Some examples: When Kate and the marshal are shown during the turbulance, note the red-haired man with the black shirt beside the marshal and other men behind, and in one shot of Kate and the marshal, a woman and man both fly up to the ceiling of the cabin. In some shots of the turbulance, when the red-haired man is seen, the marshal and Kate are gone, replaced by other passengers. Just before the tail section breaks off, men behind the red-haired guy have either changed seats or disappeared, and so forth. Row numbers seen on the luggage compartments overhead are inconsistent with passenger seating. Such as when the tail section breaks off, the man is pulled out from row 26, yet the number above reads 13, or when Claire boards the numbers overhead are 20, 21, 22, yet Jack is in row 23, which is the second row behind the wall. The interiors of the Oceanic airplane also significantly differ in various shots. One example - the seats on the airplane have blue square velcro coverings on the passengers' seat headrests, and long, wide magazine racks on the divider wall behind Locke, but when they carry Locke onto the airplane, they don't exist.

Continuity: Jin is handcuffed in season 1, "House of the Rising Sun" and the cuff remains on his left wrist until season 2, "What Kate Did" when Locke removes it. The handcuffs have a distinctive shape - a single strand connected via pivot to a double strand with the lock area. When Jin is initially cuffed to the plane wreckage, the single strand faces out at his wrist, but in following shots, in this and all the subsequent episodes, the handcuff actually switches sides repeatedly, going round his wrist the opposite way.

Continuity: 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: In the earlier shows, the positions of the cuts on Kate's and Jack's faces change, as well as their characteristics.

Continuity: When Kate finds the pilot's wingpin in the mud, the pilot's reflection is seen in the water as he lies on the branches above Kate. When Jack approaches they all look up and in the overhead shot the pilot's position differs and he lies on different parts of the branches, note their shape.

Other: The Monster appearing in the pilot and causing the turbine to explode is a mistake (not trivia). This is actually an artefact of poor CGI effects that was left in the show in error. It was confirmed by the producers. You can see it best here: http://www.lostpedia.com/wiki/Image:Turbine_Explosion.gif.

Continuity: 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.

Continuity: When Charlie, Kate and Jack are in the nose wreckage, to find the transceiver, there is a shot in first class, facing the cockpit, showing the glass wall with the decorative circular design. When Charlie is aboard the flight, running from the stewards, he stands beside that glass wall, and the circular pattern is reversed. Neither shot is flipped.

Continuity: After Jack gets Hurley and Claire away from the wing falling down, they are all lying on the ground. As Jack says "Stay with her" to Hurley, Hurley has a big lump of hair on his forehead that disappears and reappears between the shots.

Continuity: 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.

Continuity: When Charlie leaves his seat on the airplane, as he is followed by the stewards, he walks through economy (blue stripe seats), then walks through business class (grey stripe seats and roomier) - where Boone and Shannon sit. But, in Charlie's next close-up, when the plane shakes, he leans on the blue seat in front of him, which he already passed and is farther back in the plane's cabin.

Continuity: When Jack, Charlie and Kate are walking through the woods and Jack is holding the transceiver, Charlie ask if he hears anything. Jack then answers "You keep asking if there's anything", while holding the transceiver with his right hand and his left hand down. When it cuts he holds on to the transceiver with both hands.

Continuity: On the airplane, when Kate lifts the glass of juice with her handcuffed hands, in this close-up the cuff round her right wrist has the single bar facing out. However, when the turbulence hits, in another close-up of her hands, the same cuff is on the opposite way, it now has the double bar facing out.

Continuity: 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.

Continuity: When Hurley gets to Sayid who is about to fix the transmitter, Sayid puts down the battery on the case. It cuts and the battery is back in his hand and in the next shot the battery is on the case.

Continuity: 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.

Continuity: When Ray's pickup truck swerves off the road, it flips and the tailgate completely breaks off, yet in the following shots the bright red tailgate remains intact.

Continuity: When the marshal and Ray drive their vehicles down the long road, the endless line of telephone poles are on their left as they drive, with barren land on their right. However, when they pass the third vehicle the poles are on their right and then repeatedly change sides in the following shots. (This has nothing to do with camera angles.)

Revealing: As Ray drives the pickup truck, an oncoming vehicle beeps and the marshal heads behind Ray's pickup. In the shot through the cab's rear window facing the bed, as the marshal pulls behind, the bed's side wall interior is seen (note the metal loop tie down on top) and the entire tailgate is gone; yet the tailgate is intact later, when the pickup flips over. The tailgate was removed for the shot to allow visibility of the marshal's vehicle.
