Lost (2004)

Trivia: The character Sun was created specifically for Yoon-jin Kim, after she auditioned for the role of Kate but the writers felt she was not right for the role.

The End (1) - S6-E17

Trivia: the Oceanic employee delivering Jack's father's body has a name visible on his navy blue overall - it is Bocklin - Arnold Bocklin is an artist famous for painting "Isle of the Dead" in 1880. (00:04:00)

Trivia: In series 2, episode 2, at around the 35 minute mark when the camera goes underwater to show the shark swimming past, the shark has the Dharma logo on the back end of it.

Trivia: Terry O'Quinn is the only actor who didn't have to audition for the show, having previously worked with J.J. Abrams on "Alias."

Trivia: Sawyer was not originally Southern - Damon Lindelof described the original character plan as a 'slick, city con man.' It was changed specifically for Josh Holloway.

I Do - S3-E6

Trivia: In the first flashback of Kate, when she jumps into Kevin's arms, Evangeline Lilly was so enthusiastically into the scene that during one take, she accidentally knocked Nathan Fillion into the hallway wall behind him.

Born to Run - S1-E22

Trivia: When Kate runs out of the MRI room, if you look closely at the sign, instead of saying "Magnetic Resonance Imaging" as it should, it says "Magnetic Resonance ImagINing". A clue, perhaps? Too big to be an unnoticed mistake.

Man of Science, Man of Faith - S2-E1

Trivia: During the opening scene, when the camera cuts to the cabinet of drugs (shortly before the explosion heard in the distance), all the bottles of drugs have 'the numbers' on them - '4, 8, 15, 16, 23, 42'. Maybe obvious to some but worth looking out for.

The Moth - S1-E7

Trivia: In the midst of withdrawal, the third time Charlie asks Locke for his stash Locke finally hands it to Charlie, who stares at the bag of heroin. On the DVD commentary, Dom Monaghan remarks that while he holds the bag of heroin (really brown sugar, but hey) he's "doing a Gollum" - using Andy Serkis's portrayal of Gollum, and his desire for his "Precious" as the basis for Charlie's intense need for the drug.

Super Grover

Trivia: Evangeline Lilly almost wasn't cast as Kate. As a Canadian citizen, problems arose regarding her visa and Screen Actors' Guild paperwork. She managed to get everything in order the day before the pilot began shooting.

Trivia: Jorge Garcia (Hurley) missed his sister's wedding to film the show.

Pilot (1) - S1-E1

Trivia: The production budget for the 2-hour pilot was $12 million, which is far greater than most TV shows. This led to Disney firing Lloyd Braun, the ABC Entertainment Chairman, for greenlighting the show, which has now become one of ABC's biggest hits in years.

Pilot (1) - S1-E1

Trivia: When the idea was to kill off Jack in the pilot, the writers discussed Michael Keaton for the role.

Exposé - S3-E14

Trivia: The Medusa spider is not an actual spider species. It most likely got its name from the mythological creature 'Medusa' that instantly paralyzed people by looking at them and turning them into stone.

The Man Behind the Curtain - S3-E20

Trivia: In the flashback sequences, Ben's mother is played by Michael Emerson's (who portrays Ben) wife Carrie.

Trivia: Swoozie Kurtz plays Terry O'Quinn's mother in the series, even though in real life she's only six years older than him.

I Do - S3-E6

Trivia: In the DVD audio commentary, Carlton Cuse mentions that guest star Nathan Fillion had starred on "Firefly", but refers to Joss Whedon as "Josh".

Trivia: For those of you who own the Lost: Complete Collection box set and are wondering how to find the hidden disk, shining the black light on the island replica will give you a clue.

Across The Sea - S6-E15

Trivia: This was the first episode in which none of the series regulars appear in original footage. Matthew Fox, Evangeline Lilly, and Terry O'Quinn appear in archive footage from season 1, and the rest of the episode features only the credited guest stars.

Homecoming - S1-E15

Trivia: When Charlie meets the wealthy lady in his flashback scenes, she mentions that her father is buying a paper company up in Slough, an obvious reference to the UK version of "The Office" which is about a paper company in Slough.
