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.
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.

Continuity mistake: Penny's letter to Desmond changes as he reads it. The text stays the same, but the handwriting and position of the words on the page change between the two shots where you can see the letter from the front. Also, for the audience the letter is read aloud with Penny's voice. Interesting is the fact that there is one sentence omitted: "Sorry to be so dramatic, but these are dramatic times, are they not?" (You can read this sentence in both "versions" of the letter though).

Continuity mistake: Season 3, episode 2, "The Glass Ballerina". When Jin is in the hotel and is about to kill Jae Lee, he holds a pillow to Lee's head and presses his gun against it. At first, the gun is pointing to Lee's cheekbone, but when it cuts to Lee as he is sobbing "I'm sorry. I'm sorry", the gun is much lower, and pointing to his throat. Cut back to Jin, and you can see the gun is once again pointing to Lee's face. There was no time for Jin to move it between shots, and Lee did not move nearly enough to cause this changes.
Continuity mistake: After picking up Eddy the hitchhiker, John and his passenger can be seen driving through a compound. As they drive through the compound, a passenger can be seen in John's pick-up truck. The scene just before they arrive at the sweat lodge, there is no passenger.
