Matthew Fox is the ostensible star as Jack, the doctor who steps up as group leader in the first episode, but it quickly settles in as a dense ensemble show with characters who have vivid backstories:
tough, raven - haired beauty Kate, whose fair looks hide a rough outlaw past (Evangeline Lilly), con man Sawyer (Josh Holloway) who hides his bitterness under a country - boy voice and a suspicious smile, Iraqi communications specialist and Gulf war veteran (he fought on the other
side) Sayid (Naveen Andrews), steely survivalist John Locke (Terry O'Quinn), who has a mystic, one might say miraculous, connection to the island, pregnant single mother - to - be Claire (Emilie de Ravin) running from a fortune - teller's prophecy, washed - up
rock star and heroine addict Charlie (Dominic Monaghan), Korean couple Jin and Sun Kwon (Daniel Dae Kim and Yoon - jin Kim) with mob connections and no English skills (or do they?)
