20 Things You Didn't Know About LOST

Season Five just aired for the highly entertaining and ultra confusing ABC's LOST. There is so much we still don't know. We can't look into the future (unless we find the island) to figure out what's next, but we can do a little research and find some behind-the-scenes things. Here are 20 things you probably didn't know about LOST.

20. Jorge Garcia was cast as Hurley after J.J. Abrams saw him in "Curb Your Enthusiasm"

19. 4, 8, 15, 16, 23, 42 all added together equal 108, the total of minutes left to enter those very numbers into the computer each time, and the number of days that the castaways spent on the island before the Oceanic Six were rescued.

18. Charlie's shoulder tattoo reads, "Living is easy with eyes closed". This is a lyric from the song "Strawberry Fields Forever" by The Beatles.

17. The rocks used in the waterfall cave set are made of rubber so that the sound of the actors, and crew members walking about are not picked up on camera.

16. The part of Charlie was originally written for someone much older, but when Dominic Monaghan auditioned, the writers and producers loved him so much that they set about re-writing the part to Dominic's strengths.

15. The shirt that Sawyer wears that has a fish on it is from an actual restaurant. One of the show's creators went to Humpy's in Alaska and liked the logo so much he wanted to use it on the show. They didn't get permission to use it until much later so they took the logo from the site and made their own. No one at Humpy's knew how it got onto the show until much later.

14. ABC picked up the show before there even was a script. J.J. Abrams and Damon Lindelof had only turned in an outline and based on this ABC picked up the show.

13. When Jin is at the house of the person he is meant to kill, Hurley is on the television behind him. If you look (extremely) carefully you can see that he is wearing the grey shirt that he is wearing when the television cameras show up at the petrol station later on in the series.

12. Originally, Michael Emerson was only cast for a few episodes in season two. The producers were so impressed with his performance that they cast him as a regular and rewrote the part of Henry Gale/Ben to feature him more prominently.

11. In the original description for Kate, she was a slightly older woman separated from her husband, who went to the bathroom in the tail-section of the plane. However, that idea ended up being used for the character Rose.

10. The character of Sawyer was originally meant to be an older, slick, suit-wearing city con artist from Buffalo, NY. However, when Josh Holloway forgot a line at his audition and subsequently kicked a chair in frustration and loudly swore, the writers liked the edge he brought to the Sawyer character and decided to write Sawyer as more of a Southern, darker grifter instead.

9. John Locke was a 17th-century English philosopher who described the human being as "tabula rasa" - translated as "unwritten sheet" or "empty canvas" - at birth. It's obvious that the creators of the show were inspired by this when creating the character Locke.

8. Yunjin Kim originally read for the character of Kate. The producers felt she was not what they were looking for in Kate, but decided to create a new character for her, along with a spouse.

7. Josh Holloway was trying to cover up his Southern accent while shooting several of his first scenes in the first season. It wasn't until producer J.J. Abrams told him that the reason they cast him was BECAUSE of his accent that Holloway changed it. There are still some scenes left in the pilot where he doesn't use his Southern accent.

6. Adewale Akinnuoye-Agbaje came up with his own character's name, "Mr. Eko", while he and the writers were developing the character.

5. Forest Whitaker was originally cast in the role of Sawyer, but opted out of the role to direct First Daughter.

4. Jennifer Jason Leigh was approached to play the part of Libby, but she declined.

3. Ethan Rom is an anagram for "other man".

2. Matthew Abbadon is an anagram for "what bad boatmen".

1. Originally, Michael Keaton was cast as Jack. In the first draft of the script Jack was to be killed by the monster after they arrived at the cockpit. ABC told the producers that they shouldn't kill off the hero so soon in the series and the script was changed. After the change, Michael Keaton backed out of the role since he did not want to commit to a regular series.
