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)
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.
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.
Continuity mistake: At the start, we see Ana-Lucia dive into the water to help rescue people. In the close-up shot, her shirt is bunched up into a small band of material around her chest. When we see her from a long shot, her shirt is back to normal. (00:01:20)
Continuity mistake: When Ana-Lucia gives mouth to mouth on the little girl, the girls left side of the face is partially covered in sand. When it cuts her face is full of sand. (00:02:00)
Continuity mistake: When Ana realises Mr Ecko gave food to Nathan, the strand of her hair covering her face changes between shots. (00:24:20)
Audio problem: Goodwin states, "the hills are blocking it," referring to the radio signals. However, the audio is of Locke saying the line. (00:30:20)
Suggested correction: That's Brett Cullen's voice.
Continuity mistake: When Ana asks Goodwin about why they take some and not others, she has a strand of hair down the centre of her face. When the shot changes, this hair has gone. (00:31:10)
Revealing mistake: When Goodwin and Ana Lucia sits down to have a break and Goodwin hands over some fruit to Ana, she says "Where do you think they got it? I mean they're not even wearing shoes", directing to the knife. If you watch in the background you can see a car driving. (00:33:20)
Revealing mistake: During the fight between Goodwin and Ana, pay close attention to Ana just before we see them fall into the ravine. You can see some of her protective equipment visible. (00:35:20)
Continuity mistake: When Mr. Eko heads out to the water to pick up the dead bodies you see all the bodies floating face down. When it cuts there is a close up of a body that suddenly floats face up.
Continuity mistake: Ana-Lucia says that she never saw Nathan during the two hours the plane was in the air, which Cindy the flight-attendant agrees with, saying that she has a photographic memory for passengers. But the plane was actually in the air for eight hours before the crash, as revealed in the pilot, so, not only should Cindy remember him after that long, but they all should be able to tell the difference between two and eight hours.
Continuity mistake: In season 2, episode 5, Jin and Mr. Eko are searching for Michael. Jin gets attacked by a boar and rolls down a hill to find the corpse of Goodwin. In this scene they are in the middle of the jungle. Now two episodes later, when Ana-Lucia confronts Goodwin they are on top of a mountain without trees surrounding them. This is confirmed in Juliet's flashbacks in later seasons when Ben takes her to see Goodwin's body.
Collision (a.k.a.Old Habits) - S2-E8
Continuity mistake: Rose holds out some fruit to Jack. In one shot she holds it out with her right arm, then her left. (00:07:50)
Collision (a.k.a.Old Habits) - S2-E8
Continuity mistake: In the jungle while Sayid is tied up, when they are told to leave, Jin's handcuff is higher on his wrist. As he walks past Sayid the handcuff is so low around his hand that it would slip off easily. (00:26:45)
Collision (a.k.a.Old Habits) - S2-E8
Continuity mistake: Ana Lucia cuts Sayid free and chucks her knife and gun down. But we see her with the gun in the left hand and knife in the right; however, when we see them land on the floor, they're the other way round. (00:34:20)
Collision (a.k.a.Old Habits) - S2-E8
Continuity mistake: In the scene where Sun surprisingly sees Michael running out from the jungle, Sun turns and faces Michael, who is on her right. In the close-up shot followed Sun is found facing to her left. It then changes back to normal in the next shot.
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: 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)
