"We don't know where the Island went -- but now know when we'll be seeing it again. ABC insiders say that the fifth season of the Emmy-nominated cypto-drama will premiere with a two-hour event on Jan. 21, 2009, at 8 p.m. That's a Wednesday, in case you don't know next year's calendar by heart, which means that Lost will be returning to its original day-of-the-week slot. (Last season, it aired on Thursday nights.)
The Lost season five premiere will actually be a three hour event! An hour-long recap special will air at 8 PM, followed by the first two episodes from 9-11 PM. The series will air thereafter at 9 PM on Wednesdays."
