Lost

With Elizabeth Mitchell signed on to star in V, the fate of Micthell's future on Lost is certainly in question.  It definitely doesn't help that her character, Juliet, appears to have died on the season five finale.

Now, according to Entertainment Weekly's Ausiello Files, we shouldn't expect to season Mitchell appear in more than two episodes of Lost's final season.

If it helps you get over the loss, you can watch this first look at V. It actually looks pretty good!
