Lost is an American television drama series that tracks the lives of plane crash survivors on a remote, tropical island. Though the audience and survivors of Oceanic Flight 815 assumed they must have crashed somewhere between Los Angeles and Australia, as the Lost videos progress, it becomes clear that no one is really sure where -- or when -- they are.

Lost episodes are filmed on the Hawaiian island of Oahu with a large ensemble of cast members that include Naveen Andrews as Sayid Jarrah, Matthew Fox as Jack Shepard, Terry O’Quinn as John Locke, and Evangeline Lilly as Kate Austen, among others. Because of the remote location and large cast, Lost videos are one of the most expensive television shows on the air to produce. Lost clips feature the stunning Hawaiian Islands as the backdrop for extremely dramatic interactions between the characters. Complex relationships between the characters, who had nothing in common other than being passengers on a plane but are somehow all intertwined with each other and with the island, elevate the show into a supernatural mystery that keeps fans eagerly anticipating the next Lost full episode.

Lost videos also include mysterious and supernatural components, as well as recurring elements, such as the use of the colors black and white to represent the duality of many of the characters, references to dysfunctional fathers and apocalyptic references. The issues dealt with on Lost full episodes make it far more complex viewing than most standard evening fare.
