Some divorced couples need to stay far, far away from each other. And this isn't too difficult for the most part. But if they have children together they might eventually be forced to inhabit the same room for a few hours in order to witness a son or daughter's big day. In the new comedy "The Big Wedding," the situation goes a step further as the groom's mother and father (Robert De Niro and Diane Keaton) need to pretend they're still happily married. That sounds like either a recipe for disaster or a conceit that will bring them back together.

Both directions have been common ground for movies. A large subgenre of the screwball comedy involves remarriage. And many melodramas and black comedies throw exaggerated tribulations into the land of splitsville. These movies may serve as a guide for anyone looking to survive time with their ex, and below we've kicked off a helpful look at what to do and what not to do if you hope to come out of the experience with your life, or maybe even a rekindled flame.
