In Taken, Maggie Grace was the blonde who got kidnapped and taken to various exotic locations, but in a new untitled spy thriller, she'll hand over that duty to Cameron Diaz. Grace has signed on to play the sister to Diaz's character, who get kidnapped by a super spy played by Tom Cruise and taken on a worldwide journey to protect some kind of all-powerful battery.

No, I don't understand what they mean by powerful battery, nor can I really figure out how a sister fits into a story about an international spy adventure. THR only explains that filming starts in October in Boston, with James Mangold directing.
