In March 2009, Mitchell was cast in the ABC series "V", a remake of the science-fiction television miniseries. Although ABC and Warner Bros. officials said she was only cast as a guest star, the announcement led to speculation and concern that Mitchell's character would be killed off at the end of "Lost"'s fifth season, which ended on a cliff-hanger that left the fate of her character unknown. Mitchell was later named the lead actress on "V" and her character was indeed written out in the premiere of the sixth season of "Lost", but returned for the two-part series finale. "V" lasted for one more season, which premiered on January 4, 2011.
