Weddings in Movies

The big day breakdown: Allie's all set to marry charming, handsome soldier Lon Hammond — until, well, she isn't. Afraid that she may still have feelings for her long lost Summer love, Allie pays a visit to her ex Noah and finds that she's swept right off her feet.

The lesson: Feeling a bit hesitant or nostalgic is completely normal, but if you find yourself pining for someone who isn't your groom-to-be? Step back and reevaluate your feelings. And if you're struggling between the likes of Ryan Gosling and James Marsden: Good luck.
