Also making "special appearances" (we assume not in the studio) are Jorge Garcia, Josh Holloway and Evangeline Lilly. The special -- “JIMMY KIMMEL LIVE: ALOHA TO LOST”-- will also include "an exclusive look at THREE ALTERNATIVE FINAL SCENES from the minds of executive producers Damon Lindelof and Carlton Cuse."
Lindelof and Cuse have previously promised to go into hiding after the "Lost" finale airing, and won't be live in studio.
According to ABC, "'Jimmy Kimmel Live' has been deluged by more studio audience ticket requests for this special than any show in its 7 plus year history."
