Bloopers are production errors that are visible onscreen. Continuity errors are bloopers that don't match storyline or timeline from other parts of the same episode or other episodes. Confirmed bloopers and errors so far are listed below, by episode.
White Rabbit
- Charlie and Hurley are complaining to Jack about the water supply. As the three talk, there is a couple walking past behind Jack. They go by, the camera cuts to Charlie and Hurley, then back to Jack; the same couple pass by again.
House of the Rising Sun
- Jin starts a fight with Michael. Jin runs towards Michael, who is wearing the Rolex Watch. When Michael has fallen into the water with Jin in top of him, the watch is no longer there; yet when the fight is stopped by Sayid, the watch is visible again.
Homecoming
- Claire said the last thing she remembered was being on a flight from LA to Sydney, when in fact they were going from Sydney to LA.
Deus Ex Machina
- Jack's backpack changes between shots when he speaks to Sawyer. See position one and two.
Born to Run
In Born to Run, Kate is seen running through hospital doors that say "Magnetic Resonance Imagining instead of "Magnetic Resonance Imaging"
- There is a typo on a door in the hospital ("imagining" instead of "imaging").
- This could, of course, be an intentional Easter egg, as part of the Dreams and visions theme.
Exodus: Part 1
- As Rousseau aproaches the beach camp, Kate is supposed to sleep but she has her eyes open for some seconds.
- A cameraman in the water is visible in the scene as the raft leaves, and Vincent tries to follow. (Image at Humpys.net)
- On the day of Flight 815's takeoff, which was September 22nd, 2004, Walt is watching Power Rangers S.P.D. on TV. That particular show did not first air until February 2005, and didn't run in Australia until around November 2005.
Exodus: Part 2
- A boat is visible in the background as Sawyer jumps off the raft to check the rudder. (Image at Humpys.net)
Man of Science, Man of Faith
- When Jack and Locke look down into the hatch, it is at least twice as large as it was in Season 1.
- Two different versions of the Hatch door are shown, where the metal finish and stenciling of the word "QUARANTINE" varies.
- The record player inside varies between steel and wood finish, depending on the episode.
- The control panel is reversed (right-left) in two of the shots.
- The desk lamps also change models slightly through Season 3.
Adrift
A boat barely visible at top left on the horizon in Adrift.
- When Michael and Sawyer are on one of the parts of the raft, a yacht can be seen in the background. This is before Desmond leaves the island on his yacht.
- Earlier, in Man of Science, Man of Faith, when Jack goes to press a button on the computer Locke says "I wouldn't do that". In Adrift, when we see the same scene from Kate's point of view Locke says "I wouldn't do that Jack".
...And Found
- The dates on Jin's resume have the wrong years.
The Other 48 Days
A white car barely visible in the background in The Other 48 Days.
The horse trainer's hand is visible to the right side in What Kate Did.
The poorly done arrow in One of Them.
Subtitling error in The Whole Truth.
Michael's "yellow" list in Three Minutes
- During a conversation between Goodwin and Ana-Lucia, a white car is visible in the background.
- When Boone used the radio in the small plane, he heard a voice on the other end. This should have been Bernard's voice. The script is different from Boone's transmission to Bernard's. Although they are very similar, there are a few words different between them.
What Kate Did
- When the black horse appears to Kate and Sawyer, a gloved hand can be seen on the right of the screen; it's probably the horse trainer.
- There is an unconfirmed rumour that this is the hand of JJ Abrams.
- The hand was removed from the Season 2 DVD version of the episode.
- There is an unconfirmed rumour that this is the hand of JJ Abrams.
- During Kate's flashbacks, some fruit can clearly be seen marked as being from 2005.
- In the January 23, 2006 official podcast, Carlton Cuse and Damon Lindelof acknowledge this is a continuity error. The flashbacks were occurring in either 2000 or 2001.
Fire + Water
- We see John exit the Swan station by a shed door (similar to the entrance of the Arrow). However, in ?, the entrance to the Swan is comprised of two metal doors like those on the Staff entrance.
The Hunting Party
- The X-rays are incorrectly dated November 16, 2005.
The Long Con
- Jack clearly calls out "Jack!" instead of "John" when calling Locke to get the door combination from him.
One of Them
- The arrow that is in Ben's chest, shown from the front at about 18:49 clearly enters and exits his body at very different angles.
- The Gun Vault is made bigger to accomodate the Ben. It changes from a tight room to a wider room. Space is made for the bed that was not there in the beginning of the season.
The Whole Truth
- There's a grammatical error in the subtitled English ("you're" instead of "your").
- This has been fixed in repeats of the episode.
?
- Ian McVay reads from notes that are supposedly about Charlotte's post-mortem, but in actuality are the progress notes about a living female patient at Queens Hospital (in Honolulu).
Three Minutes
- The list Michael burns near the beginning of the episode is pink, when it should have been yellow, as shown later on in flashback.
- The firearm that Michael has at the beginning of the episode changes. Locke hands him a shotgun (note that it does not have sights). He knocks Locke out with the butt, then it becomes a rifle (note at this point it has sights).
Live Together, Die Alone
A close encounter with the others in Live Together, Die Alone
Desmond's Original Photograph
Desmond's Photograph, Version 2
- The Ana-Lucia/Libby funeral supposedly takes place at sunset at the end of Three Minutes, but moments later, in the opening scene of Live Together, Die Alone, the boys swim out to Desmond's boat under a bright midday sun.
- Just after the opening LOST title, when Kate is asking Jack what to tell people about the boat, the voices in the background are reversed.
- Voice 1: "How many people?" Voice 2: "How many people can fit on the boat?"
- The same audio can be heard just before the voices are reversed.
- On the lava coastline, as Desmond is wrestling with Kelvin, a crew member crouched behind some rocks is revealed by their hat peeking out. (Image at Lostvirtualtour.com)
- Two different versions of the prop used for Penelope's letter are used.
- When Eko runs out of the hatch when Locke and Desmond are faking a lock down, you see Eko put his club in his belt right in the front of his pants. In the next scene as he passes out of the door the club is gone and then when he runs back to the door as it is closing he is holding it in his hand as he drops it and it falls under the door.
- When Eko inspects the power box, we initially see that it is wide open. However, when he moves closer, it is nearly closed.
- On the Pala Ferry, Alex tries to pick up Kate, who has her hands tied behind her back and is gagged. Alex accidentally grabs Kate's breasts, quickly removes her hands, and can be seen smiling as she readjusts her hands. There is an animated GIF of the incident available at YTMND.
- When the five survivors discover the Capsule Dump on the way to attempt Walt's rescue, Sawyer's gun alternates between shots where he is holding it on his shoulder in one, and dangling it below his waist in the next.
- In the background of the Others' boat that Michael and Walt are sent out with, there is a glimpse of a small second island (real life Hawaii filming location, 'Chinaman's Hat')
- It is possible that this could be intentional to depict what we now know to be the second Hydra Island, however, not likely fitting the storyline, as this island is not supposed to be visible when Sayid, Jin and Sun visit the Pala Ferry.
- Two different actresses appear in Desmond's photograph in Man of Science, Man of Faith/Orientationand in Live Together, Die Alone. The initial photo was obviously taken prior to the casting of Penelope Widmore.
- This was confirmed to be an error when the production team correct it in the reairing of Orientation
A Tale of Two Cities
There is no explanation for why there would be an automobile on the island, or how it would get there.
- In the very lower right corner, just within range of the camera, there is a white van shown in the initial scene at Otherville, when Juliet and Ben are watching Flight 815's mid-air break-up.
- In the breakfast scene with Kate and Ben (Henry), at first the Ketchup has no label. After Ben asks Kate to put on the handcuffs, the bottle has a DHARMA logo on it. Later when Ben is putting ketchup on his eggs, the bottle again has no logo.
- When Kate first steps onto the beach she has a black band around her right wrist. By the time she sits down to put the cuffs on it is gone.
- The crossword puzzle that Jack has in his car is dated to 2006.
The Glass Ballerina
A Crew member reflection in the cabinet mirror
- Crew visible, reflected from the cabinet mirror.
Further Instructions
- When Locke wakes up after the implosion, and picks up and examines Eko's Jesus Stick, Locke is suddenly wearing his backpack and it is gone the next second.
- In the flashback, the birthdates do not match on Locke's gun license and driver's license, one of which has him at 48 (1956), and one which has him at 58 (1946).
- If Locke were 58, this would mean that his mother gave birth to him when she was 6, according to the information from her Santa Rosa Mental Health Institute papers (her birthday is 1940 there).
- Eko doesn't have the same haircut that was shown in Live Together, Die Alone. His beard is also shorter.
Debunked errors
See related article: Persistent rumors
- The flight of Oceanic Flight 815 departs at 14:55 and travels east for six hours before losing radio contact and turning the plane. This would mean that the crash would happen during the night, and yet it was during the day. DEBUNKED: They travelled eastwards, where the sun rises.
- In A Tale of Two Cities at the final zoom out before the "LOST" titles we see smoke rising out of both sides of the island where the halves of the plane landed, yet in The Other 48 Days we saw no smoke from the tail section. DEBUNKED: The tail section in the other 48 landed on the water, yet some of it landed on the jungle which we don't see in the other 48 days
- In A Tale of Two Cities Ben tells Goodwin he can make it to the tail section in under an hour "if you hurry". However, in The Other 48 Days Ana Lucia states that she saw Goodwin emerge from the jungle perfectly dry after 10 minutes. DEBUNKED: This could be 10 minutes from when Ana Lucia finally swam to the beach and got 'settled in'; not necessarily from when the plane crashed. Or this may actually be a clue.
- In Live Together, Die Alone, the number formats of the log printout have changed from the original, introduced during ?, when Locke and Eko discover The Pearl Station. When Desmond looks at the print out during Live Together, Die Alone, he sees: 922044:16 which translate to 09-22-2004 4:16. The original log contained number sequences like 41602054:05, 41602055:53, 41602088:17 which don't match the later format. DEBUNKED? This may be a continuity error or if not, then perhaps a clue.
