Through The Looking Glass Official Description

Ever drifting down the stream--

Lingering in the golden gleam--

Life, what is it but a dream?

Just a little bit of the ending of the real "Through the Looking-Glass" for you.

Here's what we can expect from LOST, though, according to the official press release.

"Through the Looking Glass" - Jack and the castaways begin their
efforts to make contact with Naomi's rescue ship, on the season finale
of "Lost,"

Guest starring are M.C. Gainey as Mr. Friendly/Tom, Tania Raymonde as
Alex, Nestor Carbonell as Richard Alpert, Blake Bashoff as Karl, Andrew
Divoff as Mikhail, Ariston Greene as Jason, Sonya Walger as Penny, Mira
Furlan as Rousseau, Brian Goodman as Pryce, Marsha Thomason as Naomi, L.
Scott Caldwell as Rose, Sam Anderson as Bernard, Lana Parilla as Greta,
Tracy Middendorf as Bonnie, James Lesure as Dr. Hamill, Nigel Gibbs as
funeral director, Loreni Delgado as pharmacist, Larry Clarke as
customer and Kate Connor as doctor.

DAMN! That's IT?! What kind of a teaser is that?!!!  ARGH!

Looks like the gangs all here so-to-speak w/ respect to the guest list.  Rousseau, Rose and Bernard (yay!), Karl and Alex, Mikhail, Alpert, the new mystery others Greta and Bonnie (they were listed in "Greatest Hits" IIRC) and Pryce, Naomi, and a funeral director?  I guess we must be going back to in between when Jack's daddio dies and he gets on the plane.

Interesting.
