18. Leonardo DiCaprio & Claire Danes
While Leonardo DiCaprio might have been able to charm the pants off of all of his female fans, the same can’t be said of his former co-star Claire Danes. The two of them starred in 1996’s Romeo & Juliet and Danes couldn’t stand to be around DiCaprio for very long. She found him to be incredibly immature and impossible to work with. Fifteen years later, she was offered a role to play Helen Gandy alongside DiCaprio’s J. Edgar Hoover in 2011’s J. Edgar, which she turned down.
