Elizabeth Mitchell vs. Aliens in V

I’m still unclear about whether or not Elizabeth Mitchell will be back as Juliet on Lost next season and, if so, in what capacity, but the trailer for her next project, V (a remake of the 1984 TV series about an alien invasion of Earth) has just debuted and I know for sure now where I’ll be getting my Mitchell fix this fall. What do you think? I think this looks pretty darned rad.
