Anyone expecting to get a glimpse into the real-life marriage of Angelina Jolie and Brad Pitt from their new movie, "By the Sea," is bound to be disappointed. And not just because it's about a squabbling couple who seem to bear little resemblance to the stars who (by all accounts) are still happy after 10 years and six kids together.

Rather, it's that film seldom captures the chemistry between actors who are a couple in real life. Or it captures something that isn't really there, at least not yet. That's why these 11 movies, which do seem to evoke on screen the real-life sparks that had already occurred off-camera, are so remarkable. Watch them with someone you love -- or used to.
