The Break-Up follows Gary Grobowski (Vince Vaughn) and Brooke Meyers (Jennifer Aniston) after they both refuse to relinquish access to their shared condo, post-breakup. What happens next can be summed up as two adults acting like children in an effort to force the other to leave. For most people, living with their ex after a break up would be described using a well-known expletive in real life. On screen, however, it's called comedy. Go figure.
