Unlike their characters in The Notebook, Gosling and McAdams' relationship wasn't exactly love at first sight. In fact, it was quite the opposite. The film's director, Nick Cassavetes, told VH1 (via Vanity Fair) that the actors got along so badly on set that Gosling wanted another actress to take the place of McAdams to practice his scenes.
"[T]hey were really not getting along one day on set. Really not," Cassavetes said. "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.'"
Cassavetes forced his actors to yell it out, which helped them move forward. He said, "The rest of the film wasn't smooth sailing, but it was smoother sailing."
