From here on, Emerson took part in many plays, such as The Misanthrope opposite Uma Thurman, and The Iceman Cometh with Kevin Spacey. After starring as a serial killer in a few episodes of The Practice, Emerson was presented with an Emmy award for Outstanding Guest  Actor.

   Emerson is probably best known for his roles in the movie Saw, and for portraying Benjamin Linus in Lost. Originally cast as a guest star, he proved a popular character and was cast as part of the usual crew for season 3.

    Terry O' Quinn, aged 54,  portrays the mysterious character Locke on Lost. He is Irish-American, and was born and raised in Michigan. He attended Michigan University and the University of Iowa, and has been in the acting business for over 30 years.

    O' Quinn has starred in such films as The Stepfather and Tombstone, as well as appearing in popular tv shows such as Miami Vice and Star Trek: The Next Generation. AFter appearing recurrantly in Alias, J.J. Abrams already had knowledge of his acting skills. He was asked by Abrams to take part in Lost, and was one of few actors who wasn't made to audition for a role.

    O' Quinn's family includes his wife, Lori, and two children, Oliver (who is 23) and Hunter (who is 21). Previously living in Maryland, they moved to Hawaii to be closer to set when production of Lost began. O' Quinn was originally named Terry Quinn; he changed his name to prevent confusion between himself and an already established actor, also named Terry Quinn.

    In his role as John Locke, O' Quinn plays the character in a similar way to other characters he has played, such as his role in The Stepfather. Locke is a quiet, mysterious character, who'd beliefs lead him more than his head. Locke's faith in (and sometimes lack thereof) the island has led him into dangerous situations many times. It is possible that the anger displayed in these situations could be attributed to the rocky relationship he had with his father, a con man.

Yunjin Kim (also written as Yoon-jin) plays the beautiful Sun on Lost.  Born in Seoul on November 7^th, 1973, Yunjin and her family moved to New York when she was a child.  A resident of New York’s Staten Island, she attended the High School of the Performing Arts.  (Remember Fame?)

Her career as an actress includes spokesperson roles, Japanese film, Korean television, and of course Lost.  She made Maxim’s “Hot 100” list of 2006 and had an amazing photo spread and cover for Stuff Magazine.

Yunjin is as complex a person as her character is, being made up of many opposites.  She is trained in many styles of dance, ranging from ballet to Afro-Caribbean.  She is proficient in many styles of fighting including broad sword and Tae kwon do.  She speaks both Korean and English fluently.  She is also a horseback rider.

Her roles on Korean television combined with her fighting abilities have earned her the nickname Yeo Chun Sa, or “The Warrior Woman.”  She has also been called the Korean Julia Roberts.

While at school she thought about changing her name to something more “Americanized.”  Instead she listened to a teacher of hers who told she should just concentrate on being a great actress.  Then people would automatically learn her name.  Seems to me the teacher was right.

Yunjin is currently living in Hawaii.

Matthew Fox (born July 14, 1966) began his adult life prepping to become a Wallstreet hawk, majoring in economics at Columbia University.   While at Columbia, Fox played footbal, wide receiver, and was a participant in a game that ended Columbia's legendary string of 44 straight loses.

After Graduating, Fox determined that the dog-eat-dog world of Wallstreet was not for him and at the recommendation of his girlfriend's mother - who was a modeling agent - Fox entered the world of acting and modeling starting out doing theater with the Atlantic Theater Company in New York.   The school is founded on the on the theory of Practical Aesthetics developed by David Mamet and William H. Macy.

Fox worked his way up through bit parts in sitcoms, an eventual big screen debut in "My Boyfriends Back", and finally into the steady work of prime-time tv as Charlie on 'Party of Five'.

Fox was cast as Jack on LOST in 2004.  Originally the part was given to actor Michael Keaton, and Jack was to have died a shocking death in the pilot.  After that idea was scrapped, Keaton backed out wanting nothing to do with the workload of a prime-time big network series.

Matthew Fox had originally sought to play the character of Sawyer, but lucky timing with the unexpected departure of Keaton opened him up for what many consider to be the largest role on the series.

As LOST rocketed to unrivaled success, so did Matthew Fox's reputation eventually landing him roles in major Hollywood productions such as McG's 'We Are Marshall' and the upcoming political thriller Vantage Point.
