Season 4 was planned (prior to the Writers Guild of America strike) to feature 16 episodes, to be broadcast beginning in the U.S. and Canada on January 31, 2008.[13] Due to the writers’ strike, the season will instead last only 14 episodes, consisting of the 8 pre-strike episodes already filmed and aired, and 6 post-strike hours airing beginning April 24 in the United States. This includes a 3-hour finale airing in three parts entitled “There’s No Place Like Home.” The first part will aired on Thursday, May 15 10 pm ET, and parts 2 and 3 will air in a 2-hour special airing on May 29, from 9-11 pm ET.

The face-off between the survivors and the freighter people continues, and the Oceanic Six find themselves closer to rescue, on the two-hour Season Finale!
Look for Ken Leung as Miles, Daniel Dae Kim as Jin, Yunjin Kim as Sun, and Naveen Andrews as Sayid.
