...And Found - S2-E5
Continuity mistake: When Jack calls Sun on the beach, there is no one near her. When the shot changes to a close-up, someone is walking past her. (00:07:40)
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.
...And Found - S2-E5
Character mistake: When Sun rips up her garden, she sits down with her arms crossed and head against her arms. In these shots, the position of her hands, the dirt on her hands, the dirt on her watch, all change between shots. (00:22:30)
Continuity mistake: When Hurley's mum is trying to wake him up, the position/way he's holding his ticket changes. (00:06:20)
Exodus (1) - S1-E23
Visible crew/equipment: When Michael tells people to push the raft, a crew member with a white shirt and camera is visible clear as day by the bushes on the beach. (00:07:50)
The Greater Good (a.k.a. Sides) - S1-E21
Continuity mistake: When talking to Hassam while playing football, Sayid has a strand of hair in front of his face that keeps appearing and disappearing. (00:20:50)
The Greater Good (a.k.a. Sides) - S1-E21
Continuity mistake: When Sayid puts his hand on Jack's shoulders, the camera changes to a different angle and now his hands are no longer on his shoulders. (00:10:30)
The Greater Good (a.k.a. Sides) - S1-E21
Continuity mistake: When Sayid puts his hands on Jack's shoulders just after the funeral, the position of his hand and how his fingers are positioned changes between shots. (00:10:30)
The Greater Good (a.k.a. Sides) - S1-E21
Continuity mistake: Charlie, Sawyer and Kate restrain Jack at the funeral, and Kate has her hands on his chest. Camera cuts, and she's now a few steps away from Jack. (00:09:30)
House of the Rising Sun - S1-E6
Revealing mistake: When Charlie is stood on the bee hive, all the bees are clearly CGI. (00:10:00)
Continuity mistake: In the scene where Eko is walking up to the church and the woman tells him if he buys a statue the money will pay for a polio vaccine for the village, he is wearing an earring in his right ear. Once inside the church talking to his brother, his is wearing the earring in his left ear.
Factual error: The neurosurgeon introduces himself as "Doctor" Woodruff and also has this written on his coat. In Australia, where this scene is set, surgeons are always addressed and referred to as "Mister" after the British fashion.
The End (1) - S6-E17
Audio problem: When Desmond, Locke and Jack are standing outside the cave with light, Desmond says "maybe I can find a way out for you too," or something like that. Jack replies, "there are no do-overs." The camera then goes to over Jack's right shoulder as he says, "I tried that once." However, the words don't match what his mouth is saying.
Continuity mistake: When Miles is sent to deliver "The Package" (i.e. the dead body) to Dr. Chang, after the body is taken out of the van, Miles is seen closing the door to the back of the van. After a return from a flash forward and back to 1977, the door to the back of the van is open again.
Continuity mistake: Season 6, episode 8 "The Package": When Charles Widmore hands Jin the camera and tells him to turn it on, the lens is already out, therefore the camera is already on. When the shot cuts away you can hear him turning the camera on and the motor extending the lens.
Live Together, Die Alone, Part 2 - S2-E24
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).
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)
