One hundred and twenty-one episodes of Lost aired between September 22, 2004, and May 23, 2010. J. J. Abrams (pictured), who co-created the American television series with Damon Lindelof, directed the pilot episode, which was based upon an original script titled Nowhere written by Jeffrey Lieber. Six seasons of the show aired, in addition to numerous clip shows to recap previous episodes. The series follows the experiences of the survivors of a plane crash on a passenger jet, Oceanic Flight 815, which crashed on a tropical island in the South Pacific, with each episode typically featuring action on the island as well as a secondary storyline from another point in a character's life. Lost: Missing Pieces consists of thirteen original two-to-three minute clips referred to as "mobisodes" which were produced for cell phones and released between seasons three and four. Multiple former and recurring cast members made an appearance in the series finale. (Full list...)
