8. Ryan Gosling & Rachel McAdams in The Notebook
When watching this movie, no one would ever guess that these two didn’t get along. They had so much chemistry on screen that it seemed impossible that they wouldn’t be a couple off-screen as well.

Eventually, the director had them talk it out and while it seemed to help, the rest of the film wasn’t all smooth sailing.
