It's important in any working environment to get along with your coworkers. It's even more important if your entire job is convincing the world that you and your coworker are undyingly in love. Thus, the chemistry read was born. This is how so many celebrity couples get together because some casting director somewhere did their job a little too well. In spite of rounds of auditions meant solely to ensure that a central couple will get along in front of the cameras, some onscreen couples grow to really, really dislike each other off-screen.
Some actors are so talented, we would never guess that they couldn't be in the same room with each other. For others, it's a little more clear, even in their films. In the most extreme cases, actors have left well-paying gigs because they just could not stand the sight of their costar any longer. We live for drama. Take a look at some of the on-screen couples who didn't like each other IRL.
