The runaway hit of ABC's 2004-2005 TV season, the weekly, hour-long drama series Lost began at a point that in any other case may have been an ending: a passenger jet was torn apart in mid-air, crashing on an uncharted Pacific Island. Stripped of all vestiges of the civilized world, the 48 survivors were forced to fend for themselves in their new tropical surroundings, which departed from the "norm" for similar castaway dramas by boasting a bizarre and frequently incomprehensible topography, not to mention a most unusual variety of wildlife -- include at least one polar bear! Among the principal survivors were Dr. Jack Shephard (Matthew Fox); fugitive Kate Ryan (Evangeline Lilly); has-been rock star Charlie Pace (Dominic Monaghan); the reclusive and mysterious John Locke (Terry O'Quinn); hot-tempered and self-serving James "Sawyer" Ford (Josh Holloway); chauvinistic Korean husband Jin Kwon (Daniel Dae Kim) and his much-put-upon wife, Sun (Yunjin Kim); resourceful former Iraqi Republican Guard Sayid (Naveen Andrews); estranged siblings Shannon Rutherford and Boone Carlisle (Maggie Grace, Ian Somerhalder) -- she's a bitch, he's a control freak; dad Michael Dawson (Harold Perrineau) and his sullen young son, Walt (Malcolm David Kelley); roly-poly comic relief Hugo "Hurley" Reyes (Jorge Garcia); and very pregnant Aussie Claire Littleton (Emilie de Raven). Forced to rely upon one another to stay alive, this diverse group shares a number of sinister secrets and oft-unsavory interrelationships, with the truth behind each character revealed piecemeal via flashbacks and little-unexpected twists of plot. Adding to the suspense, at least during the series' first season, was the apparent presence of a person not on the passenger list, who seemed determined to bump off the hapless castaways one by one, and a mysterious, terrifying yet unseen monster-like creature. Co-created by J.J. Abrams of Alias and Felicity fame, Lost debuted on September 22, 2004. ~ Hal Erickson, Rovi
