Lost: Missing Pieces

Lost: Missing Pieces is a series of thirteen video clips ranging in length from one to four minutes that aired during the hiatus between the 3rd and 4th seasons of the television show Lost, from which the series is spun off. They generally became available to Verizon Wireless users on Mondays from November 2007 to January 2008 and were uploaded onto the ABC's website a week later for free streaming. The "mobisodes", which have also been referred to as "webisodes", were shot in Honolulu, Hawaii, and produced by the same crew with the same cast as the television series; thus, all content is considered to be canonical. Lost: Missing Pieces were included as special features in the fourth season's 2008 DVD releases.

The project was announced in November 2005 as the Lost Video Diaries; however, production was delayed several times due to contractual restrictions. Lost's writer-producers originally proposed the mobisodes as a self-contained story that would focus on two previously unseen characters of the Lost fictional universe. These characters would be played by actors who were not part of the Screen Actors Guild; however the entertainment guilds refused to support such a project. After months of unsuccessful negotiating, the series was seemingly shelved by ABC. In June 2007, it was announced that the mobisodes, which would be renamed Lost: Missing Pieces, would star the regular characters of Lost in thirteen short video clips unrelated to each other. Twelve scenes were newly shot; one was a deleted scene from the television series. Critical response to Lost: Missing Pieces was mixed. The series was nominated for an Emmy Award in 2008.
