Ryan Gosling and Rachel McAdams are talented actors, because The Notebook shows no signs of behind-the-scenes strife.

According to director Nick Cassavetes, the co-stars' chemistry on set wasn't as evident as it was when the movie was released in theaters. "Maybe I'm not supposed to tell this story, but they were really not getting along one day on set. Really not," he recalls to Vh1. "And Ryan came to me, and there's 150 people standing in this big scene, and he says, 'Nick come here.' And he's doing a scene with Rachel and he says, 'Would you take her out of here and bring in another actress to read off camera with me?' I said, 'What?' He says, 'I can't. I can't do it with her. I'm just not getting anything from this."

Realizing the movie hinged on the actors' performances, Cassavetes held an impromptu therapy session.
