ABC once again invites new and avid "Lost" viewers to take another look at one of the most talked about and critically acclaimed shows. "Lost Clip Show" (working title) will explore the series in a way that will bring new viewers up to date -- but which current viewers will also find illuminating - in anticipation of the two-hour fifth season premiere. The special will take an in-depth look at the mysteries of the island, its inhabitants, the Oceanic 6, outside influences such as Charles Widmore, and also delve into some of the questions that have been answered, and others that still remain a mystery.
