The Time Traveler's Wife, the latest blockbuster book turned movie, leaves nothing to chance in its trailer. If you've never read the award-winning book, have no fear: The trailer will clear that up. The movie stars Eric Bana as a librarian who responds to stress by spontaneously time traveling and Rachel McAdams as his wife, whom, we see, he visits (via time travel) as a child. Bana even watches their relationship as it deteriorates. Don't let the chick-flick narrative (love, happiness, major bump in the road, reconciliation) fool you: There's a magical element present in the story.
